Question 117212: Solve the system by graphing.
x – 2y = 8
x + y = –1
Answer by checkley71(8403) (Show Source): You can put this solution on YOUR website!
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)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = x/2 -4 and y = -x -1).
(2,-3) are the intersection points.
