using the graphical solution procedure to find the optimal solution and value of the objective function for a given linear program.

Consider the following linear program.
Min8X + 12Ys.t.1X + 3Y ≥ 62X + 2Y ≥ 86X + 2Y ≥ 12X,Y≥ 0
(a)
Use the graphical solution procedure to find the optimal solution.
What is the value of the objective function at the optimal solution?
at (X, Y) =   
(b)
Assume that the objective functio
