Question 6887
Since these equations are fairly simple, you can graph them by finding two points for each one that satisfy the equation and then draw a line through them.
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).
