Answer:

(0, 0)

Step-by-step explanation:

Since we have an equation with y on one side by itself, the easiest method to use here is substitution.

2x + 4y = 0

2x + 4(-8x) = 0

2x − 32x = 0

-30x = 0

x = 0

Plug this into either equation to find y.

y = -8x

y = 0

The lines intersect at (0, 0).
