Answer:

The correct answer is D. -4

Explanation:

In order to find this, we need to solve for x when y = 0. This will give you the x intercept.

-5x + 10y = 20

-5x + 10(0) = 20

-5x = 20

x = -4

Answer:

D. -4

Explanation:

-5x+10y = 20

To find the x intercept set y = 0 and solve for x

-5x+0=20

-5x = 20

Divide by -5

-5x/-5 = 20/-5

x = -4
