Finding the slope between two points why does the slope formula work

The video tutorial introduces the concept of slope, explaining how to plot points on a graph and connect them. It defines slope as the change in Y values over the change in X values, often referred to as rise over run. The tutorial demonstrates how to calculate slope using both a graph and the slope formula, emphasizing the importance of consistency in calculations. The video also covers how to handle situations where a graph is not available, using subtraction to find differences in coordinates.
