Midpoint and Slope Calculations

The video tutorial explains how to calculate the slope, distance, and midpoint between two points on a graph. It uses a right triangle to visualize these calculations and demonstrates the process using specific coordinates. The tutorial covers the use of the Pythagorean theorem for distance and averaging for the midpoint, and it generalizes these methods for any two points.
