Graphical Method |Part 1| Linear Programming-Unique and Alternate/Infinite Solution

This video is about Graphical Method for solving Linear Programming Problem with two variables. To find the optimal solution either we can find objective function value at all corner points or we can draw the objective function line to trace the best (Optimal) corner point. I have explained how to find corner points and how to draw the objective function line.  For above,  I have considered examples of LPP which gives Unique Solution and Alternate solution. If there exist an alternate optimal solution, then there exists infinite optimal solutions.
