In this lesson, we learn how to find the rate of change from a graph, specifically with linear graphs. The rate of change is defined as a ratio of the change in two quantities, which is the slope of the graph. We can find the slope by taking the difference between two y-values and two x-values, or by visually examining the graph and counting the change in y and x values from left to right or right to left. Both methods will give us the same slope.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
