The linear programming problem has an unusual characteristic. Select a graph of the solution region for the problem and describe the unusual characteristic. Find the maximum value of the objective function (if possible) and where it occurs.
?
Objective function:
?
z = x + y
?
Constraints:
?
x ? 0
y ? 0
-x + y ? 1
-x + 5y ? 7
?
