In this lesson, we learn how to find the rate of change in a real-life problem by analyzing a graph. By using the formula for rate of change, we can determine the slope of the graph and understand how quickly the balloon is descending. We also learn that a negative slope indicates that the graph is going down as we move to the right.

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.
