What is slope interception form?
Y=mx+b, where m is the slope and b is the y-intercept, is the slope intercept form. The graph of the linear equation can be drawn on the x-y coordinate plane using this form of the equation.
For the given question we are given,
slope (m) = 2/3
and we are also given the point that the line passes through to be,
(-1,3).
that is
(x,y)=(-1,3)
x=-1
y=3
we, know that slope interception form is of the form,
y=mx+c
substituting the value of m (slope) and the point (-1,3) we get
3=(2/3)*(-1)+b
= 3= -2/3 +b
= 3+2/3=b
= (9+2)/3=b
= 11/3=b
from this we get b=11/3
now substituting this again in
y=mx+b
we get
y=(2/3)x+(11/3)
Hence the second option [tex]y=\frac{2}{3}x +\frac{11}{3}[/tex] is correct.

Answers
There were 707 representatives who attended political gatherings from each country in South America.
We have been given that a political gathering in South America was attended by 8,475 people.
Each of South America's 12 countries and 3 territories were equally represented.
The number of representatives attended from each country is the ratio of the total number of people in the gathering to the total number of countries.
The number of representatives :
⇒ total number of people in the gathering / total number of countries
The number of representatives = 8,475 / 12
The number of representatives = 706.25 ≈ 707

The sequence of transformations needed to transform the parent function f(x) into the linear function g(x) = 6 - 2x is given as follows:
Reflect over the x-axis, vertically stretch by a factor of 2, and then shift up 6 units.Reflect over the y-axis, vertically stretch by a factor of 2, and then shift up 6 units.Linear function and transformationA linear function is defined according to the following rule:
y = mx + b.
In which:
m is the slope of the function, which is by how much y changes by when x changes by 1.b is the intercept of the function, which is the value of y when x = 0.From the stated graph, we have that when x = 0 and y = 6, and when x increases by 1, y decays by 2, hence the function is defined as follows:
y = -2x + 6.
The parent function is:
f(x) = x.
Then, to generate the transformed function, we have that:
x -> -x, hence the function was reflected over any of the axis.-x -> -2x, hence there was a vertical stretch by a factor of 2.-2x -> -2x + 6, meaning that the function was shifted up 6 units.Using these three bullet points, the correct options were chosen.

How to solve variable related problems?1. Switch the positions of the variables in the equation. Starting with "solving for x" (or any other variable) in one of the equations, this "substitution" approach begins. [2] Say your equations are, respectively, 4x + 2y = 8 and 5x + 3y = 9.
2. To "solve for x," divide both sides of the equation.
3. Reconnect this to the other equation. Don't use the equation you just employed; rather, return to the other one.
When a particular variable's value is given to you
we just have to substitute that value in the required equation.

Using the properties of parallel lines we find the value of x is 9 and the value of y is 13.
In geometry, parallel lines are coplanar, straight lines that never intersect.
Any parallel planes in the same three-dimensional space are those that never intersect. Parallel curves are those that have a predetermined minimum separation between them and do not touch or intersect. If a line and a plane in three-dimensional Euclidean space do not intersect at a point, they are also said to be parallel. On the other hand, skew lines are two noncoplanar lines. A transversal is a line that crosses across two other lines in the same plane at two separate points. Transversals play a crucial role in establishing if two or more other lines in the Euclidean plane are parallel.15). In the given figure the two angles represented by 12x+1 and 15x -26 are equal. as they are alternate exterior angles.
We know from the property of parallel lines that they are equal.
Therefore:
12x+1 = 15x -26
or, 12x-15x = -26-1
or, -3x = -27
or, x = 9
Therefore the angles are 12x + 1 = 109
Now,
109 + 4y-9 +28 =180
or, 4y = 180 - 128
or, y = 13.
Therefore as the line l and m are parallel the value of x is 9 and the value of y is 13 .

K = -1
We need to find the, linear factors of the polynomial when it is given that k = -1 is a zero of the given polynomial
So, we got that ( x +1 ) is a one linear factor of P(x). As the highest degree of the polynomial is 3 so there will be three zeroes of the given polynomial. Therefore, We need to find others two
If we divide P(x) = [tex]x^{3}[/tex] - 2[tex]x^{2}[/tex] - 7x - 4 by ( x + 1 ) by long division method we'll get, [tex]x^{2}[/tex] -3x - 4
Now we'll solve the quotient by squaring method, to get the other two
Let's say h(x) = [tex]x^{2}[/tex] -3x - 4
h(x) = [tex]x^{2}[/tex] -3x - 4
h(x) = [tex]x^{2}[/tex] -( 4 -1) x - 4
h(x) = [tex]x^{2}[/tex] -4x + x - 4
h(x) = x( x-4) + 1( x -4 )
h(x) = (x+1)(x-4)
