Lesson: Parallel and Perpendicular Lines

Example Problems of Parallel and Perpendicular Lines

Examples to Try!

1.) One line passes through the points ( -1, -2) and ( 1, 2)

     Another line passes through the points ( -2, 0) and ( 0, 4)

Are these lines parallel, perpendicular, or neither?

2.) Write the equation for the line that passes through ( 3, 6) and runs parallel to the line y = (2/3)x - 4.
