Answer:

Graph 1 : y  = 5x +3

Graph 2: y = -3x -8

Step-by-step explanation:

Graph 1:

y-intercept, b = (0,3) = 3

slope between (-2,-7) and (0,3)

m = (3--7)/(0--2) = 10/2 = 5

Equation is therefore

y = mx + b = 5x +3

Graph 2:

y-intercept, b = (0,-8) = -8

slope between (-4,4) and (0,-8)

m = (-8-4)/(0--4) = -12/4 = -3

Equation:

y = mx + b = -3x -8
