Solving Systems of Equations by Graphing

  • You can solve a system of equations by graphing the equations and finding the point of intersection of the two graphs.

  • If the graphs are parallel lines, there is no point of intersection and no solution to the system.

  • If the graphs are the same lines, the system has an infinite number of solutions.

  • If the graphs intersect at one point, the system has a unique solution.
