Question

Simplex method of solving linear programming problem uses (a) all points in the feasible region

Answer 1

Any linear programming problem involving two variables can be easily solved with the help of graphical method as it is easier to deal with two dimensional graph. All the feasible solutions in graphical method lies within the feasible area on the graph and we used to test the corner points of the feasible area for the optimal solution i.e. one of the corner points of the feasible area used to be the optimal solution. We used to test all the corner points by putting these value in objective function.
