Provide an appropriate response.Explain why the solution of a system of equations is the point of intersection of the graphs of the equations.
What will be an ideal response?
Each point on the graph corresponds to an ordered pair that is a solution of the equation. The point of intersection of the graphs of two lines corresponds to an ordered pair that is a solution of both equations and, hence, a solution of a system of equations.
