About This Lesson
http://www.freemathvideos.com In this video series I show you how to graph parallel and perpendicular lines. We do this by understanding the characteristics of parallel and perpendicular lines. Parallel lines do not touch and have the same slope. Perpendicular lines intersect at a point that create a 90 degree angle. Their slopes are opposite reciprocals of each other. Often we refer to perpendicular lines as orthogonal. To determine parallel or perpendicular lines we use either the point slope equation or slope intercept equation to input the correct slope. We then plug in our given point for x and y and then solve for the equation of the line. Learn math your way.
