Geometry 3-8 Guided Practice: Slopes of Parallel and Perpendicular Lines

10

Solve It! You and a friend enjoy exercising together. One day, you are about to go running when your friend receives a phone call. You decide to start running and tell your friend to catch up after the call. The red line represents you and the blue line represents your friend. Will your friend catch up?
