Solving for Slope with the Slope Formula

This video tutorial explains how to find the slope using the slope formula y2-y1 over x2-x1. It begins with a review of finding slope from a graph, emphasizing the rise over run method and simplifying fractions. The tutorial then demonstrates finding slope using ordered pairs, highlighting the importance of handling negative numbers correctly. The video concludes with a final example, reinforcing the concepts taught.
