The slope of the line is 3/7.
The slope of line will be calculated using the formula :
Slope = [tex] \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
The first point is (-2, 7) and second point is (-9, 4). So, [tex] y_{2}[/tex] = 4, [tex] y_{1}[/tex] = 7, [tex] x_{2}[/tex] = -9 and [tex] x_{1}[/tex] = -2. Keep the values in formula to find the values of slope of the line.
Slope = (4 - 7)/(-9 - -2)
Performing subtraction in numerator and denominator
Slope = -3/-7
Cancelling the negative signs we get -
Slope = 3/7
Thus, the slope of the line is 3/7.

DUE TODAY ASAP!! Megan has $50 and saves $5.50 each week. Connor has $18.50 and saves $7.75 each week. After how many weeks will Megan and Connor have saved the same amount?
Include step by step explanation for brainliest.
If Megan has $50 and saves $5.50 each week. Connor has $18.50 and saves $7.75 each week. Then after 14 weeks Megan and Connor have saved the same amount.
What is Equation?Two or more expressions with an equal sign is called as equation.
Let x=the number of weeks
For Megan we have:
50+5.5x
For Connor we have:
18.50+7.75x
Let us equate Megan's and Connor to have same amount.
50+5.5x=18.50+7.75x
Let us take variables on one side and numbers on other side.
50-18.50=7.75x-5.5x
31.5=2.25x
Divide both sides by 2.25
x=14
Hence after 14 weeks Megan and Connor have saved the same amount.

There are 750 students in the seventh grade class and 625 students in the eighth grade class at Brookland Middle School. There are 1,375 total students at the school. About what percent of students attending Brookland MIddle School are in seventh grade? Help asap!!
The percentage of students in Brookland Middle School who are attending seventh grade is 54.54%
What is percentage?
In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it. A% is a number that has no dimensions and is dimensionless (pure).
We know that, to get the value of percentage we have to divide the value for which percentage needs to be calculated by total value and then multiply the resultant by 100.
So, we will divide the number of student in seventh class by the total number of student and then multiply it with 100.
(750/1375)100 = 54.54 %
Therefore, percentage of students attending Brookland Middle School are in seventh grade is 54.54%.

What is the equation of the line that passes through the point
(3,-7) and has a slope of -4/3
Using point-slope form, the equation is [tex]y+7=-\frac{4}{3}(x-3)[/tex].
Answer:
y = - [tex]\frac{4}{3}[/tex] x - 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - [tex]\frac{4}{3}[/tex] , then
y = - [tex]\frac{4}{3}[/tex] x + c ← is the partial equation
to find c substitute (3, - 7 ) into the partial equation
- 7 = - 4 + c ⇒ c = - 7 + 4 = - 3
y = - [tex]\frac{4}{3}[/tex] x - 3 ← equation of line

Which inequality represents the values of x that ensure triangle abc exists? a triangle with side lengths of 6.5 units, 3.5 units, and 2.5 + x units
The inequality that represents the values of x that ensure the triangle ABC exists is 0.5 < x < 7.5
Inequality is a term used in mathematics to represent a relation that makes an unequal comparison between two functions.
As the lengths of the sides of the triangle are 6.5 units, 3.5 units, and 2.5 + x units, we can use the property which states that the sum of two sides of the triangle is always greater than the third side, therefore;
6.5 + 3.5 > 2.5 + x
10 > 2.5 + x
10 - 2.5 > x
x < 7.5
Now we use the property which states that the difference between two sides of the triangle is always less than the third side of that triangle as follows;
6.5 - 3.5 < 2.5 + x
3 < 2.5 + x
3 - 2.5 < x
0.5 < x
Now we combine both values as follows;
0.5 < x < 7.5
Therefore the inequality that represents the values of x is 0.5 < x < 7.5

Step-by-step explanation:
Liam buys some fruit for £26.55 by paying 2 notes of £20 and £5 and 3 coins of 50 cent and one coin of 5 cent.
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Given:
Liam buys some fruit for £26.55.
He pays the exact amount using two notes and four coins.
So, possible notes are £1, £5, £10 and £20.
And the possible coins are 1¢, 5¢, 10¢, 25¢, 50¢, and £1.
So, through trial and error,
we get notes of £20 and £5.
And the coins are three coins of 50 cent and 1 coin of 5 cent.
The total amount = adding the amount of notes and coins.
£26.55 = £20 + £5 + 3(50¢) + 5¢
Therefore, notes of £20 and £5 and the coins are three coins of 50 cent and 1 coin of 5 cent, Liam used.

Select the equation for the line in point-slope form.
Answer:
(d) y -8 = -5/8(x +8)
Step-by-step explanation:
You want the point-slope equation for the line through the points listed in the table.
Point-slope formThe point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
ApplicationThe first point listed in the table is (h, k) = (-8, 8), so the equation will be of the form ...
y -8 = m(x -(-8))
y -8 = m(x +8)
Comparing this form to the answer choices, we see that it matches choices (b) and (d). These have m = -8/5 and m = -5/8, respectively.
SlopeThe slope of the line is given by the formula ...
m = (y2 -y1)/(x2 -x1)
m = (4 7/8 -8)/(-3 -(-8)) = (-3 1/8)/5
Clearly the magnitude of this is less than 1, so cannot match m=-8/5, which has a magnitude greater than 1. The appropriate answer choice is (d):
[tex]\boxed{y-8=-\dfrac{5}{8}(x +8)}[/tex]
__
Additional comments
The slope can be worked out to be ...
(-3 1/8)/5 = (-25/8)/5 = -5/8
This confirms our answer choice.
We know the magnitude of (-3 1/8)/5 is less than 1 because 3 1/8 < 5.

Some information is given about each sphere. Order them from least volume to greatest volume. You may sketch a sphere to help you visualize if you prefer. Sphere A: Has a radius of 4 Sphere B: Has a diameter of 6 Sphere C: Has a volume of 64 Sphere D: Has a radius double that of sphere B.
The least volume to greatest volume will be sphere B, sphere C, sphere A and sphere D.
What will be the volume of the sphere?The volume of the sphere is calculated as:
= 4/3 πr³
where r = radius
The volume of sphere A will be:
= 4/3 πr³
= 4/3 × π × 4³
= 85.3π
The volume for sphere B will be:
= 4/3 πr³
= 4/3 × π × (6/2)³
= 4/3 × π × 3³
= 36π
The volume for C is given as 64π.
