Answer:

#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:

Answer:

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.
