Perpendicular Bisectors and Slope Concepts

The video tutorial guides viewers through finding the equation of the perpendicular bisector of segment AB, where A is (-6, -3) and B is (2, 1). It explains the concept of a perpendicular bisector, calculates the midpoint of the segment, finds the slope of the segment, and determines the perpendicular slope. The tutorial then derives the equation of the perpendicular bisector using the point-slope form and demonstrates graphing the line. The instructor, Mario, encourages viewers to practice and explore more examples on his YouTube channel.

What is the first step in solving the problem of finding the perpendicular bisector of segment AB?
