Chapter 3: Parallel and Perpendicular Lines
3.4: Proofs with Perpendicular Lines
EQ: How do you write equations of parallel and perpendicular lines?
Parallel lines have the same slope and perpendicular lines have slopes that are opposite reciprocals (see theorems on p157).
Examples #2, 3 and 4 will help on the prep work.
