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
