Lesson Summary:

This lesson teaches you how to solve systems of equations using graphing. The tutor shows how to graph two linear equations in slope-intercept form, and how to find the intersection point, which is the solution. The lesson emphasizes the importance of checking the answer to make sure it's a true statement. If you're struggling with solving systems of equations, graphing is a useful tool, and this lesson is an excellent resource to help you master it.

    This video shows how to graph lines that are in slope-intercept form and find their intersection point. You do not always have to change standard form equations into slope-intercept form to graph, but that is the method used in this video.
