Question 302069
-2x + 3y = 6
3Y=2X+6
Y=2X/3+6/3
Y=2X/3+2 (RED LINE)
2x + 3y = 18
3Y=-2X+18
Y=-2X/3+18/3
Y=-2X/3+6 (GREEN LINE)
{{{ graph( 300, 200, -6, 5, -10, 10, 2x/3 +2, -2x/3 +6) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions 2x/3 +2 and -2x/3 +6). 
SOLUTION (3,4)
