This algebra math tutorial explains how to solve system of equations by graphing. The first step is to graph each equation on the same coordinate plane. If the lines intersect, the point of intersection is a solution to the system of equations. If they are parallel, the system has no solutions. If they are coincident, the system has infinitely many solution. Throughout the video, we will work through various examples, including equations given in standard form and slope-intercept form, and system of equations that has no solutions and infinitely many solutions. We will also see how to verify/check the solution.
