Lesson Summary:

In this lesson, students learn how to graph linear equations by finding the x and y intercepts. The teacher emphasizes the significance of the intercepts and teaches how to identify them on a graph. By plugging in zero for x and y, students can easily find the intercepts, solve for the variables, and plot the points on the coordinate plane. By connecting the points, students can quickly and easily graph the linear equation.

Lesson Description:

Finding the x and y intercepts and then graphing the equation using the intercepts

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.

Questions answered by this video:
  • What does x-intercept mean?
  • What does y-intercept mean?
  • How do I find the x and y intercepts of a line from an equation?
  • How do I graph a line once I know the x and y intercepts?
  • What are the x and y intercepts of 3y=9x-12?

    This lesson teaches what x and y intercepts of a line are, and it shows how to find them from an equation. Then, it shows how to graph the line once you know the intercepts.
