Calculating Slope: Practice Problems and Techniques

This video tutorial guides viewers through calculating the slope from tables, graphs, and ordered pairs. It includes three rounds of exercises, each focusing on a different method of finding the slope. The video emphasizes the concept of 'change in y over change in x' and covers special cases like undefined and zero slopes. Viewers are encouraged to practice quickly and accurately, with a timer to simulate fast-paced problem-solving.
