Because any two points determine a straight line, you need to have two ordered pairs to draw the line defined by y=x-1. Just pick any value of x you want and substitute it into the equation to solve for y. Do that again to get a second ordered pair, plot both of your points (ordered pairs), and connect with a straight line. The graph is: graph%28300%2C300%2C-5%2C5%2C-5%2C5%2Cx-1%29
