Here is a graph and WHY it has perpendicular and parallel lines in it and how you can tell.

**How is it Parallel?**
This graph has parallel lines because all three of the equations have 3/4 as the same dominate.

**How is it Perpendicular**
The line crossing through called perpendicular is perpendicular because the equation is flipped around as 4/3 with a negative.

//Make sure it has 90 Degree angles such as M<ABC=90 Degrees//
