Question 74719: Solve each of the following systems by graphing.
x-2y=8
3x-2y=12

You can put this solution on YOUR website!
x-2y=8 Solve for y
y=%281%2F2%29x-%281%2F4%29
3x-2y=12 Solve for y
y=%283%2F2%29x-6
So now we can graph the equations
+graph%28+300%2C+200%2C+-2%2C+10%2C+-10%2C+10%2C+%283%2F2%29x-6%2C+%281%2F2%29x-%281%2F4%29%29+
So the intersection looks to be about (6,2), but that's just an estimate. If you evaluate with your graphing calculator, you get the solution (5.75,2.625) which is exact.
