Unit 4 Concept 5 Writing equations of Parallel and Perpendicular

Watch the video closely. This concept is a review of algebra 1. We are writing equations of lines that are parallel and perpendicular to a line you are given. Read the steps below first before watching the video.

1. First, I solve the given equation for "Y" if it is not in slope intercept form so I can find the slope

2. Second, I find the needed slope. Parallel---same slope Perpendicular----opposite flipped

3. Third, Use the slope I need and the point I am given to plug into **y = mx + b **and SOLVE FOR "b"

4. Finally write your new equation with you **new slope** and **new b. **
