Explanation
Choice B is correct. If a point lies on both lines in the graph of a system of two linear equations, the ordered pair is a solution to the system. The graph shown is the graph of a system of two linear equations, where the two lines in the graph intersect at the point . Therefore, the point lies on both lines, so the ordered pair is the solution to the system.
Choice A is incorrect. The point lies on one, not both, of the lines in the graph shown.
Choice C is incorrect. The point lies on one, not both, of the lines in the graph shown.
Choice D is incorrect. The point lies on one, not both, of the lines in the graph shown.
