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.
