Graph A.
Graph B.
Graph C.
Graph D.
Compare your answer:
Your answers may vary,, but here are some samples.
- Graph A is the only set of graphs that represents a system of equations. It is the only system with exactly one solution.
- Graph B is the only set of graphs that represents a system of inequalities with no solutions.
- Graph C is the only set of graphs in which the boundaries are horizontal and vertical lines. It is the only one representing a system with an infinite number of solutions.
- Graph D is the only graph that does not represent a system. It only represents one inequality.
