Graphing Two Lines on the Same Coordinate Plane

When you graph two lines on the coordinate plane, sometimes they will intersect. When they do, how can you determine the exact coordinates of the point of intersection? If you find the proper point, and then substitute the x and y values back into each of the original equations, you should end up with true statements, like 5 = 5.

This idea is explained well in your text book. See Lesson 7.1.
