Find the slope (m) and the y-intercept (b) of the given line on the graph.

pls show work/explanation!

Step-by-step explanation:

Equation of a Line

Given two points through which a line passes, it's easy to find the equation of the line in the form

where m is the slope, and b is the y-intercept.

We are given the graph of the line and two clearly marked points to work with: (-4,4) (4,8)

We'll use the point-point formula to build the function of the line

Plugging in the coordinates

Operating

Simplifying

Rearranging

Here we can say

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
