Question

A system of equations is graphed on the coordinate plane.

y=−2x−4
y=2x+4

What is the solution to the system of equations?

Enter the coordinates of the solution in the boxes.

Answer 1

y = -2x - 4
y = 2x + 4

-2x - 4 = 2x + 4
-2x - 2x = 4 + 4
-4x = 8
x = -8/4
x = -2

y = 2x + 4
y = 2(-2) + 4
y = -4 + 4
y = 0

solution (-2,0)
