Lesson Summary:

This lesson teaches how to determine when a slope is zero and undefined on graphs. By finding the change in X and Y coordinates and dividing them, we can calculate the slope. If the numerator is 0, then the slope is 0. However, if the denominator is 0, then the slope is undefined. It's important to understand that dividing by 0 gives an undefined value.

Lesson Description:

Given three graphs determine when the slope is zero and undefined

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.
