Writing Equations of Parallel and Perpendicular Lines
1. Determine the equation of a line parallel to the given line through the given red point. Input your equation into the input bar to see if it looks correct. click the "show parallel line" box to see if you are correct.
2. Determine the equation of a line perpendicular to the given line through the given red point. Input your equation into the input bar to see if it looks correct. click the "show perpendicular line" box to see if you are correct.
3. Move the red point and both of the line parameters and try another problem.
4. Repeat so you do 2 different lines that are parallel and perpendicular.
