Question

Solve the system of equations by graphing. y=-2x y=-3x-2 A.(4,-2) B.(-2,4) C.(1,-1)D.(-1,1)

Answer 1

y = -2x

for x = 0 → y = -2(0) = 0 → (0, 0)

for x = 2 → y = -2(2) = -4 → (2, -4)

y = -3x - 2

for x = 0 → y = -3(0) - 2 = 0 - 2 = -2 → (0, -2)

for x = -2 → y = -3(-2) - 2 = 6 - 2 = 4 → (-2, 4)

Look at the picture.

Answer: B. (-2, 4)
