Graphing and Slope: Finding Slope from Two Points

This video tutorial explains how to calculate the slope of a line given two points. The slope, represented by 'm', is calculated as the rise over the run, or the change in y-values over the change in x-values. The video provides two examples: one with a positive slope and another with a negative slope, demonstrating the use of the slope formula y2-y1/x2-x1. The tutorial emphasizes understanding the slope's direction and its implications on the graph's behavior.
