A company produces two products, X and Y. Product X requires at least 4 hours of labor and 5 units of raw material, while Product Y requires at least 3 hours of labor and 2 units of raw material. Graph the inequalities for labor and raw material constraints and determine the feasible region for production.

• The feasible region is the area on the graph where the inequalities intersect, representing all possible combinations of products X and Y that can be produced without exceeding labor and raw material limits.

• The feasible region is the area where only product X can be produced.

• The feasible region is determined solely by the labor constraint.

• The feasible region includes all points on the graph without any restrictions.
