Midpoint Formula and Averages

The video tutorial explains how to find the midpoint of a line segment using the midpoint formula. It begins by introducing the problem of finding the midpoint between two points, (-1, 3) and (5, -1). The midpoint formula is explained as the average of the x-coordinates and y-coordinates of the given points. The tutorial then demonstrates how to apply the formula by plugging in the coordinates, simplifying the calculations, and arriving at the final midpoint, which is (2, 1).
