I have been trying to figure out how to solve a problem like this, but I can not figure it out. Could someone please explain it to me step by step?

(-7,-9) and (-2, -8)

equation of the line in slope-intercept form is y=

slope = (-8-(-9))/(-2-(-7))= (-8+9)/(-2+7) = 1/5

Equation of the line

(y-(-9))= 1/5(x-(-7))

(y+9) = 1/5 (x+7)

5(y+9) =(x+7)

5y+45 =x+7

5y =x+7-45

y = 1/5* x-38/5
