Explore Parallel and Perpendicular Lines
Activity Overview
Students will use a graphing calculator to explore graphs of parallel and perpendicular lines. Students will find that parallel lines have the same slope and different y-intercepts and that the slopes of two perpendicular lines are opposite reciprocals of each other.
This Technology Lab accompanies Lesson 3-6 from the ©2007 Holt, Rinehart and Winston Geometry textbook.
