Answer by checkley71(8403) (Show Source): You can put this solution on YOUR website!
X-Y=5 OR -Y=-X+5 OR Y=X-5 (RED LINE)
X+Y=3 OR Y=-X+3 (GREEN LINE)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions Y = -X -5 and Y = -X +3).
-------------------------------------------------------------
X-2Y=8 OR -2Y=-X+8 OR Y=-X/-2+8/-2 OR Y=X/2-4 (RED LINE)
X+Y=-1 OR Y=-X-1 (GREEN LINE)
