Solve the system by graphing.
x – 2y = 8
x + y = –1
------------
Solve each equation for y:
y = (1/2)x -4
y = -x - 1
---------------
Plot two points for each graph and draw a line thru them:
For y=(1/2)x-4, if x=0,y=-4; if x=2,y=-3
------------
For y=-x-1, if x=0,y=-1; if x=2,y=-3
---------------
================
