Finding Slope from a Graph

This video tutorial teaches how to find the slope from a graph using the concept of rise over run. It covers different types of slopes: positive, negative, zero, and undefined, with examples for each. The tutorial emphasizes using a right triangle to determine the rise and run, and how to use a calculator to convert results into fractions or decimals. It also highlights the importance of identifying 'pretty points' on a graph for accurate calculations.
