Lesson Summary:
In this lesson on parallel and perpendicular lines, the instructor explains the differences between these two types of lines and how to determine whether lines are parallel or perpendicular. The lesson also covers how to write parallel and perpendicular equations, and how to find slopes of lines to identify relationships between parallel and perpendicular lines. The instructor demonstrates how to use this information to solve application problems and provides helpful tips and examples throughout the lesson.

Staff Review
What does it mean for lines to be parallel? When are two equations for lines perpendicular? If these questions are not clear to you, you may want to check out this video. Good visual explanations with colored lines to show when lines will be parallel or perpendicular, and how to predict with just an equation. The extra practice resource has some good practice problems to assist you as well. -
