Every solution of this equation is a point on this line. The method we used at the start of this section to graph a linear equation is called plotting points, or the Point-Plotting Method. You can use two points to graph a line, but if you use three points, and one is incorrect, the points will not line up. This tells you something is wrong and you need to check your work.
