    This lesson takes you on a step-by-step tutorial for solving a system of equations by graphing. The lines are already in slope-intercept form, so all that is necessary is to graph the lines by plotting the y-intercept, plotting a second point using the slope, drawing the line between the points, and finding their intersection.
