At about the 0:15 mark, the teacher says we're gonna find out where this graph crosses the x-intercept and where it crosses the y-intercept; he should have said x-axis and y-axis.

Lesson Summary:

In this lesson, we learn how to graph an equation using the x and y intercepts. By finding where the graph crosses the x and y axes, we can plot our line accurately. To find the x-intercept, we set y to zero and solve for x, while for the y-intercept, we set x to zero and solve for y. By connecting the two points, we can create a straight line that represents our equation.

Lesson Description:

Graphing an equation in standard form using the x and y 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.

    This lesson explains what the x-intercept and the y-intercept are. It then shows how to find the intercepts by using an equation, and lastly, it shows how to graph the line using the intercepts.
