The graph of a system of linear equations is shown. What is the solution to the system?
Explanation
Choice B is correct. A solution to a system of equations must be the solution to each equation in the system. It follows that if is a solution to the system, the point lies on the graph in the xy-plane of each equation in the system. The point that lies on each graph of the system of linear equations shown is their intersection point . Therefore, the solution to the system is .
Choice A is incorrect. The point lies on one, but not both, of the graphs of the linear equations shown.
Choice C is incorrect. The point lies on one, but not both, of the graphs of the linear equations shown.
Choice D is incorrect. The point lies on one, but not both, of the graphs of the linear equations shown.
