Slopes Of Parallel Lines

In this activity your goal is to make the blue line parallel to the red line. You are given the red line and two points on the line A and B. You can use either to figure out what the slope should be for blue line if we want them to be parallel. When you have determined what the slope of the blue line should be, type it in the text box at the top and click on the "check answer" box. It will tell you if you are correct if not.
