What is the slope of the line that passes through the points (2, 8) and
(-3, 14)? Write your answer in simplest form.
Answer:
-6/5
Step-by-step explanation:
slope = (y_2 - y_1)/(x_2 - x_1)
slope = (14 - 8)/(-3 - 2)
slope = 6/(-5)
slope = -6/5
The solution is -6/5
The slope of the line that passes through the point A ( 2 , 8 ) and B ( -3 , 14 ) is slope m = -6/5
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the first point be A
Now , the value of A is A ( 2 , 8 )
Let the second point be B
The value of B is B ( -3 , 14 )
And , the slope of the line between 2 points is given by the formula,
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 14 - 8 ) / ( -3 - 2 )
On simplifying the equation , we get
Slope m = 6 / ( -5 )
Slope m = -6/5
Therefore , the slope of the line is m = -6/5
Hence , The slope of the line that passes through the point A ( 2 , 8 ) and B ( -3 , 14 ) is slope m = -6/5

What kind of transformation converts the graph of f(x)=3x+9 into the graph of g(x)=3x–10?
The transformation of the functions from f(x) to g(x) is translate 7 units right and 2 units up
How to determine the transformation?The equations of the functions are given as
f(x) = 3x + 9
g(x) = 3x - 10
Let the translations from f(x) to g(x) be h and k
So, we have
g(x) = f(x + h) + k
This gives
f(x + h) = 3(x + h) + 9 + k
Open the brackets
f(x + h) = 3x + 3h + 9 + k
Substitute f(x + h) = 3x + 3h + 9 + k in g(x) = f(x + h) + k
g(x) = 3x + 3h + 9 + k
This means that
3x + 3h + 9 + k = 3x - 10
Evaluate the like terms
3h + 9 + k = - 10
This gives
3h + k = - 19
Express -19 as -21 + 2
3h + k = -21 + 2
Express 21 as 3 * 7
3h + k = -3 * 7 + 2
By comparison, we have
h = -7 and k = 2

12. x = 109°
13. (b) 84
14. (c) 96
15. C
Step-by-step explanation:
11. Parallel means that if the lines continued on forever, the lines will never cross. They have the same slope.
12. x is an alternate exterior angle to the angle labeled 109°. this means that the angles are equivalent.
13. y is the last unknown angle in the triangle. The interior angles of a triangle always add up to 180°. So 180° = 55° + 41° + y.
y = 180° - 55° - 41° = 84°
14. z is a supplementary angle to y, meaning that y + z = 180°.
180° - 84° = 96° = z
15. Lines d and c are parallel meaning they have the same slope, therefore if you know the slope of one, you know the slope of the other.

a local salesman receives a base salary of $875 monthly. he also receives a commission of 10% on all sales over $1800. how much would he have to sell in a month if he needed to have a monthly income of $1500?
The total sell in a month if salesman needed to have a monthly income of $1500 is $894657.14.
What is termed as the sales commission?Sales commission is indeed the amount of cash as well as money paid to salespeople for exceeding a predetermined sales target. For instance, a company may agree to pay it's own salespeople a 4% commission on monthly sales exceeding Y.The total monthly earnings for salespeople can be calculated as follows:
Monthly salary = base salary + sales commission
Given that what a local salesman generates a base salary of $875 and a 10% sales commission on any and all sales above $1,800, the salesman must make the following sales in order to earn $1500 in a given month:
Let the sales done by 'x'.
Then,
875 + 7% (x - 1800) = 1500
875 + (7/100) (x - 1800) = 1500
7(x - 1800) = 62500
x - 1800 = 8928.7
x = 894657.14

write the equation of the line that is perpendicular to 5x-4y=4 and passes through the point (-8, 2)
The linear equation perpendicular to 5x-4y=4 is:
y = (-4/5)*x + 42/5
How to get the linear equation?We want to find a line perpendicular to:
5x - 4y = 4
Solving this for y, we get:
y = 4 - 5x
y = (4 - 5x)/-4 = -1 + (5/4)*x
We can see that the slope of this line is 5/4, the slope of a perpendicular line will be the inverse of the opposite, so we get:
slope = -4/5.
Then the line is something like:
y = (-4/5)*x + b
To find the value of b, we use the fact that the line passes through (-8, 2)
2 = (-4/5)*-8 + b
2 = (-32/5) + b
2 + 32/5 = b
10/5 + 32/5 = b
42/5 = b

The midpoint of AB is M(1, 1). If the coordinates of A are (-2,5), what are the
coordinates of B?
The coordinates of B are (4 , -3) .
A cartesian coordinate system, which uses signed distances between two fixed perpendicular oriented lines and the point measured in the same unit of length, uniquely identifies any point in a plane by a pair of numerical coordinates.
The origin of each reference coordinate line, known as an axis of the system or simply an axis (plural axes), is the intersection of the ordered pairs (0, 0). The coordinates can also be determined by looking at the locations of the perpendicular projections of the point onto the two axes, which are shown as signed distances from the origin.Let the coordinates of B be (x, y)
As M is the mid point of AB , we know from the distance formula that the coordinates of M will be:
abscissae of M = (-2 + x) /2
or, 1 = (-2 + x) /2
or, x = 4
Ordinate of M = (5 + y)/2

The statement that shows the correct measure of ∠A'B'C' is
m∠ABC = m∠A'B'C'.
What type of transformation does rotation do?
Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point. A rotation produces a new figure known as the image. The picture matches the original figure exactly.
The rotation will typically be at a similar angle, even if a figure can be rotated by any number of degrees. Positive degrees will cause the figure to revolve counterclockwise. The graphic will turn clockwise if the degree value is negative. Any point on the figure can be rotated.
Given, ΔABC with co-ordinates (3, 4), (5, 3) and (3, 2); also ∠ABC = 53.13°
Again, ΔABC is rotated counter-clockwise by 90° to make the ΔA'B'C'.
Thus, new triangle having co-ordinates (-4, 3), (-3, 5) and (-2, 3) is obtained.
Rotation retains congruence since it is a transformation that does not alter side length or angle measure.
Thus, we have ∠A'B'C' = 53.13°
Therefore, ∠ABC = ∠A'B'C' = 53.13° i.e. m∠ABC = m∠A'B'C'.

In statistics, the term "linear model" has several meanings depending on the situation.
Since it refers to regression models the most, the phrase is frequently used synonymously with a linear regression model. When used in time series analysis, the phrase has a different meaning. In each case, "linear" refers to a subclass of models for which it is possible to significantly reduce the complexity of the underlying statistical theory.The water balloon is hurled from a height of 40 feet above, as can be seen from the linear model.
The balloon now ascends to a height of 70 feet before returning to ground due to gravity.
The balloon drops to the earth and makes a splash after about ten seconds.
Therefore, the balloon will remain at the ground for some more time.

Peter biked 2 fewer kilometers than Jackson.Drag and drop the expressions into the boxes to write an expression that represents the total number of kilometers Jackson, Maria, and Peter biked in all.------ + ------ + ------k812k + 10k + 8k + 2k−8k−2
We already know that Jackson biked k kilometers.
Maria biked 8 more kilometers than Jackson, which means that she biked
[tex]k+8[/tex]Peter biked 2 fewer kilometers than Jackson, which means that he biked
[tex]k-2[/tex]To get the total all of them biked, we add those expressions together.
[tex]k+(k+8)+(k-2)[/tex]2. Write ONE algebraic rule that represents triangle JKL being translated to triangle J"K"L".
The original coordinates of JKL:
J(-3, -3), K(-4, 2) and L(2,1)
First, it is translated by the algebraic rule (x,y)->(x+2, y-3):
J(-3, -3)-> J'(-3+2, -3-3)=J'(-1, -6)
K(-4, 2) -> K'(-4+2, 2-3)= K'(-2, -1)
L(2,1) -> L'(2+2, 1-3)= L'(4, -2)
Then, this image is translated by (x,y)-> (x-2, y-1)
J'(-1, -6) -> J''(-1-2, -6-1) = J''(-3, -7)
K'(-2, -1) -> K''(-2-2, -1-1)= K''(-4, -2)
L'(4, -2) -> L''(4-2, -2-1)= L''( 2, -3)
Coordinates for triangle J''K''L'':
J''(-3, -7), K''(-4, -2) and L''( 2, -3)
2. To find algebraic rule that represents JKL to J''K''L'':
[tex]\begin{gathered} J^{\doubleprime}(-3,-7)\text{ and J(-3, -3)} \\ (x,y)\rightarrow(x,\text{ y+4)} \end{gathered}[/tex]
