For y = x + 2 it would go like this: When x=0, y=2. There's one point -- (0, 2). When y=0, x must be -2. There's a second point -- (-2, 0). Draw the line. You do the same thing with the second equation. (I hope you get answers of (0,2) and (1,0)!) Where the two graphed lines cross is a point that is on both lines. This is what a solution is: the same (x, y) is true in both equations. In this case these lines share the point (0, 2).
