Basics of Parallel and
Perpendicular Lines
Slope of Parallel and
Perpendicular Lines - Part 2
Slope of Parallel And Perpendicular Lines - Part 1
In this video, I explain how lines are parallel and perpendicular using slope. I discuss how parallel lines have the same slope, and how perpendicular lines have slopes that are negative reciprocals. I explain how to find the negative reciprocal of slopes. I go over 4 different example problems, one being plotting and proving lines are parallel and perpendicular just by using their slopes.
The video might take a little while to play. Please be patient.
