- What does parallel mean?
- What does perpendicular mean?
- How can you tell if lines are parallel?
- How can you tell if lines are perpendicular?
- How do you write an equation for a line parallel to another line through a point?
- How do you write an equation for a line perpendicular to another line through a point?

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.

This video show a lot way and it help!

Great vid; this helped a lot. You taught this better than my teacher in a video!!! Thank you so much; I finally understand!

thank you for putting it on mathvids.com one more thing better than my math toutor

great pacing. well done
