Question
In Graphical solution the feasible solution is any solution to a LPP which satisfies.
  1. Only objective function.
  2. Non - negativity restriction.
  3. Only constraint.
  4. All the three
✓

Answer

  1. Non - negativity restriction.
Solution:
The feasible region is the set of all the points that satisfy all the given constraints.
The variables of the linear programs must always take the non - negative values (i.e., $\text{x}\geq0$ and $\text{y}\geq0$).
These are used because x and y are usually the number of items produced and we cannot produce the negative number of items.
The least possible number of items could be zero.
Therefore, the feasible solution should satisfy the non - negativity restriction.
