Question 183328
2x + 3y = 9
3y=-2x+9
y=-2x/3+9/3
y=-2x/3+3
{{{ graph( 300, 200, -6, 5, -10, 10, -2x/3 +3) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, -2x/3 +3).
------------------------------------------------ 
slope=-2/3
y intercept=3 (0,3)
0=-2x/3+3
2x/3=3
2x=9
x=9/2
x=4.5 is the x intercept. (4.5,0)
