The video tutorial explains how to calculate the slope of a line using the formula M = (y2 - y1) / (x2 - x1). It provides examples with different sets of points to demonstrate both positive and negative slopes. The tutorial emphasizes identifying and labeling coordinates before substituting them into the formula, and it highlights the importance of understanding the vertical and horizontal changes between points.
