PRACTICAL STEPS INVOLVED IN SOLVING LPP BY GRAPHICAL METHOD
The practical steps involved in solving linear programming problems by Graphical Method are given below:
| Step 1 → | Consider each inequality constraint as equation. |
| Step 2 → | Take one variable (say x) in a given equation equal to zero and find the value of other variable (say y) by solving that equation to get one co-ordinate [say (0, y)] for that equation. |
| Step 3 → | Take the second variable (say y) as zero in the said equation and find the value of first variable (say x) to get another co-ordinate [say (x, 0)] for that equation. |
| Step 4 → | Plot both the co-ordinates so obtained [i.e., (0, y) and (x, 0)] on the graph and join them by a straight line. This straight line shows that ... |
