Finding the Solution to an Equation by Graphing
In this lesson, we are shown how to find the solution to an equation by graphing. The first step is to graph the equation, and then find where the lines intersect. To do this, we can use either the x and y intercepts, or the slope intercept form. By finding the intersection point of the two lines, we can determine the solution to the equation. If the lines intersect at every point, then the solution is infinite.

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 solution of a system of equations is graphically, and the teacher talks about what the solution is when the two equations actually represent the same line.
