The problem asks to minimize the expression $-5x + 2y$ over a bounded feasible region, which is represented graphically.

Steps to solve:

1. Identify the vertices of the feasible region: The solution to linear programming problems on a bounded region typically occurs at one of the vertices of the polygon formed by the constraints.

   From the graph, the vertices of the polygon appear to be:

   • $(1, 0)$
   • $(4, 7)$
   • $(8, 7)$
   • $(9, 0)$

2. Evaluate the objective function at each vertex:

   • At $(1, 0)$: $-5(1) + 2(0) = -5$
   • At $(4, 7)$: $-5(4) + 2(7) = -20 + 14 = -6$
   • At $(8, 7)$: $-5(8) + 2(7) = -40 + 14 = -26$
   • At $(9, 0)$: $-5(9) + 2(0) = -45$

3. Determine the minimum value:

   • The values of the objective function at each vertex are:
     • $(1, 0): -5$
     • $(4, 7): -6$
     • $(8, 7): -26$
     • $(9, 0): -45$

   The minimum value is $-45$, which occurs at the vertex $(9, 0)$.

Conclusion:

The minimum value of $-5x + 2y$ is $-45$, and it occurs at $(9, 0)$.
