At about the 1:14 mark, the teacher says where does the line cross the y intercept; he should say where does it cross the y axis.
At about the 2:39 mark, the teacher says where it crosses the x intercept; he should have said the x axis.
At about the 2:50 mark, the teacher says that it crosses where x=2.5; he should have said -2.5.
In this lesson, you will learn how to find the x and y intercepts of a linear equation using a graph, a table, and an equation. The y intercept is the point where the graph crosses the y-axis, and the x intercept is the point where the graph crosses the x-axis. In a table, the x intercept occurs when the y value is zero and the y intercept occurs when the x value is zero. When given an equation, you can find the x and y intercepts by plugging in zero for the corresponding variable and solving for the other variable.

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.
