Perpendicular Bisectors and Midpoints

The video tutorial explains how to find the equation of a perpendicular bisector for a line segment with endpoints (1, 2) and (3, 6). It covers calculating the slope of the segment, finding the perpendicular slope, determining the midpoint, and using these to write the equation in point-slope form. The tutorial also demonstrates converting the equation to slope-intercept form and graphing it to verify accuracy.
