Select a couple (arbitrary) values for x and for each solve to get corresponding y values; plot each set of coordinates; draw a line through those coordinates.

Explanation:

I used x=0 and x=4 as being fairly easy values to solve for y:
color(white)("XXX"){: (underline(x),color(white)("XX"),underline(y)), (color(red)0,,color(red)(-3)), (color(green)(4),,color(green)(-8)) :}
