Finding Unit Rates from Graphs

This video tutorial teaches how to find unit rates using graphs. It covers the concept of unit rates, common mistakes, and three methods to calculate them. Examples are provided to illustrate the process, including scenarios with breaks in scales and unlabeled axes. The lesson concludes with a summary of the key points.
