In this lesson, you will learn how to find the rate of change or slope of a graph by examining the changes in the x and y variables. If given two points, you can determine the slope by finding the change in y over the change in x. However, if the points are not clearly visible on the graph, you can write them as coordinate points and use the slope formula to solve for the rate of change. This method can be useful for more complex problems.
How to determine the rate of change using a graph
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.
Questions answered by this video:
How do you find rate of change from a graph?
How can you find the slope of a line from a graph?
If a line goes through the points (0, 3) and (5, 0), what is the rate of change or slope of the line?
What does rise/run mean?
How can you use the slope formula to find the slope of the line given points (0, 3) and (5, 0)?

This lesson shows how to find the rate of change or slope of a line by using two points on the graph of the line. Rise/Run is used to calculate the slope. There is some talking in the background that is distracting, however.
