Graphing a System of Equations using Intercepts
In this lesson, you will learn how to graph a system of equations using the intercepts. Rather than solving for y, you can find the intercepts by setting x or y to zero and solving for the other variable. Then simply plot the two intercepts on a graph and connect them to get the solution. This method is particularly useful when dealing with fractions, making it an important tool to have in your math arsenal.
How to graph a system of equations 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.

Staff Review
This lesson shows an example problem taking two equations, finding the intercepts, and making a rough graph of the equations. Each step involved in solving for x and y in each equation and graphing them is shown. The intersection point is not found exactly, but the solution is estimated based on the rough graphs.
