Please help me with this math homework question. I really can not figure this out.

Extracted text: Shown in the diagram is an unbounded feasible set formed by 3 inequalities. The corners of the feasible set are all points with integer coordinates. Find the locations, i.e. the ry-coordinates, of the max and min of the objective function 2x – 7y on this feasible set. 5. 4 3. -3 -2 -1 -1 2. 4 7.
