Solve the problem.A homeowner wants to plant a flower garden and a vegetable garden on two separate square plots of land. She determines that the length of the vegetable garden is to be at least 1 meter longer than the length of the flower garden and that the combined area of the two gardens is not to exceed 81 square meters. Write a system to represent the situation, letting x represent the length of the flower garden and y represent the length of the vegetable garden. Then graph the system.
