How To: Use rise over run to graph a straight line

Use rise over run to graph a straight line

In this video the tutor shows how to graph a straight line using the rise over run method. The rise over run trick allows you to graph a straight line as long as you have a starting point and a slope value in the form of a fraction. The first step is to graph the starting point. In the second step he states that the numerator of the slope is rise and the denominator of the slope is run. He says that the rise is vertical and the run is horizontal and shows how do rise and run using those values on the graph. Arriving at another point, he joins it to the original point there by arriving at the graph of the straight line.
