Identify the Solution to a System of Equation Given a Graph, Then Verify (Example)

Curated and Reviewed by Lesson Planet

Is the solution really the solution? Given a graph of a linear system, an informative video shows learners how to determine the solution as the point of intersection. The presenter verifies the solution as a solution to the system by evaluating both equations at the solution point to determine whether the equations are truly equal.
