x intercept = -4

y intercept = -2

Explanation:

2x+4y=-8

Divide by -8

x/-4 + y/-2 =1

x intercept = -4

y intercept = -2

Graph of the above equation is as follows:

I would first solve the equation for y.

Explanation:

2x + 4y = -8

4y = -8 - 2x

y = -2 -(1/2)x

Now simply choose a few values for x and solve for y. The intercepts will be both the coordinates determined by the x and y value.
