3x-y=1
-y=-3x=1
y=3x-1
------------------------
3x-y=2
-y=-3x+2
y=3x-2
------------------------
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = 3x -1 and y = 3x -2).

3x � y = 1
3x � y = 2
Okay, here's how you do it. I used the slope formula, y = mx + b. First you need to get y by itself, that way you can graph. So for the first one, 3x - y = 1, you're going to move the x over to the right, making it -y = -3x + 1. You need the y to be positve, so divide by a negative, or change the signs of everything. Now you have y = 3x - 1. The y intercept is -1 so put a point at (0,-1). Then you can use a T-Table or the slope. I use the slope because it's easier, so here is how you can do it with the slope:
Change the 3 to 3/1, that way you know the rise and the run, so from the point (0,-1), go up 3 and right 1, and then do it again and make your line!
