2X+Y=2
Y=-2X+2 THIS EQUATION IS A LINE WITH A SLOPE OF -2 & A Y INTERCEPT OF 2.
WE NOW HAVE ONE SET OF POINTS (0,2) THE Y INTERCEPT.
SETTING Y=0 WE CAN FIND ANOTHER SET OF POINTS.
0=-2X+2
-2X=-2
X=-2/-2
X=1 OR ANOTHER POINT IS (1,0)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = -2x +2).
