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