BIll is mostly correct, but 12 / 3 = 4.

4x+3y=-12

Move all non y values to the right:

3y=-4x-12

Divide both sides by 3:

y=-(4/3)x-4

Sorry for the previous error. Was working it out in a rush.

4x -3y = 12 -3y = 12 - 4x 3y = -12 + 4x y = -4 + 4/3x

4x + 3y = -12
3y = -4x - 12
y = (-4x - 12)/3
y = -4x/3 - 12/3
y = -4/3(x) - 4

3y = - 12 - 4x

y = - 4 - (4/3) x
2009-09-25 4:38 pm
4x+3y=-12
4x-4x+3y=-12-4x
3y=-12-4x
3y/3=-12/3-4x/3
y=-4-(4/3)x
