Last question.
If I have found all of the linear equations and have all of the intersection points for this feasible region, how do I calculate the maximum and minimum using the given function
f(x,y)=x+3y?

If this function f(x,y) is the function for which you have a set of x,y then calculate each f(x,y) and see which is max or min. There shouldn't be that many intersecting points to test.

Thanks, I hope that's it.
