In part 3 of solving linear systems of equations with two variables, students learn how to solve systems of equations by graphing. This method involves graphing two linear equations on the same graph and finding their intersection. There are three possibilities for the intersection of the lines: they intersect at one point, they are parallel (meaning no solution), or they are the same line (meaning infinitely many solutions). Through an example problem, students learn how to graph two lines and find their point of intersection to solve the system.
