Question 247195
-4x-2y=-12 
4x+8y=-24
my favorite question
add the two equations and you eliminate x because 4x-4x=0
then substitute your answer for y in either equation and you find where they intersect.
to graph them
hint: Do one equation at a time 
set x to zero and get y e.g. -4x-2y=-12 becomes -2y=-12 y=6
set y to zero and get x 

and plot those four points and draw the lines.

Do that for both equations
