1. Get into y = mx +b form2. State old slope3. State new slope (same m because it is parallel)4. Plug-in point and new slope into point slope form

1. Get into y = mx +b form2. State old slope3. State new slope (negative reciprocal m because it is perpendicular)4. Plug-in point and new slope into point slope form

To find an endpoint, given a midpoint:

*Remember to state your answer as acoordinate pair!

1. M = Midpoint

2. S = Slope (old slope of given line segment)

3. P = Perpendicular Slope (new slope/negative reciprocal slope)

4. P = Plug-in midpoint and new slope into point slope form
