Given the following points, write the equation of the line that goes through them. ( -12,56), (0,8), and (8,-24).
BaLLatris [955]

Answer:

y=-4x+8

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

take two points from the data

(0,8), and (8,-24).

substitute

m=\frac{-24-8}{8-0}

m=\frac{-32}{8}

m=-4

step 2

Find the equation of he line in slope intercept form

y=mx+b

we have

m=-4

b=8 ----> the y-intercept is given

substitute

y=-4x+8
