In this lesson, students learn how to graph a linear equation using a table. The instructor shows how to find the x and y intercepts and then demonstrates how to set up a table and pick easy numbers to create four points that lie on the same line. The lesson stresses the importance of only needing two points to create a line and the simplicity of choosing easy numbers between negative two and positive two when creating a table.
Graphing a linear equation using a table
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.

This lesson begins with a review of how to graph a line by finding the intercepts. Then it goes into how to create a table of values from an equation, and it shows how to graph the line once you have a table of values.
