Perpendicular Bisectors and Slope Concepts

The video tutorial explains how to find the equation of a perpendicular bisector. It begins with an introduction to the problem, followed by graphing the segment and calculating its midpoint. The tutorial then covers how to calculate the slope of the segment and find the perpendicular slope. Finally, it demonstrates forming the equation of the perpendicular bisector using the point-slope form.
