At about the 0:22 mark, the teacher says that the x intercept is when the graph crosses the y axis; he should have said that it is when the graph crosses the x axis.
In this lesson, you will learn how to graph linear equations using a table and equation. The instructor demonstrates how to plot points on a coordinate grid using x and y intercepts while explaining the significance of each. The lesson concludes with two examples of how to graph a line using the methods taught.

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.
