Exploring Rate of Change and Slope Concepts

This video tutorial explains the concept of rate of change, which is equivalent to the slope of a graph. It covers how to calculate the rate of change from a table using the formula of change in y divided by change in x. The tutorial also demonstrates how to determine the slope from a graph, emphasizing the importance of understanding the rise over run concept. Various examples are provided to illustrate these calculations, ensuring a comprehensive understanding of the topic.
