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.
