Lesson Summary:

In this lesson, students are shown how to find the slope on a graph by using a slope triangle. The instructor explains that to find the slope, the change in y-values over the change in x-values needs to be calculated. The instructor then demonstrates how to create a slope triangle and how to determine the change in y and x values. Additionally, the instructor walks through an alternative method of finding slope algebraically.

Lesson Description:

Using a slope triangle to find the slope on 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.
