Answer:

C. (-2, 0)

Explanation:


y = 3x + 6


y = 2x + 4

Since both equations equal y, set them equal to each other.


3x + 6 = 2x + 4


x + 6 = 4


x = -2

Substitute -2 for x in the first equation.


y = 3x + 6


y = 3(-2) + 6


y = -6 + 6


y = 0


(-2, 0)

Now, substitute the x- and y-values into the second equation.


y = 2x + 4


0 = 2(-2) + 4


0 = -4 + 4


0 = 0

It works! The soluton to the system of equations is (-2, 0).
