You can
put this solution on YOUR website!graph these four feasible regions of the system: (a) x ≤ (1/2) y, x + y ≤ 1000, x ≥ 0, y ≥ 0
-----------------
You need to graph the boundaries of the inequalities which are
always EQUALITIES:
Graph:
For x<=(1/2)y, graph the boundary of y>=2x which is y=2x.
Shade the half-plane above the boundary line.
--------------
For x+y<=1000, graph the boundary of y<=-x+1000 which is y=-x+1000
Shade the half-plane below the boundary line.
----------------------
For x>=0 shade the half-plane to the right of the boundary which is x=0.
---------
For y>=0, shade the half-plane above the boundary which is y=0.
-----------
The graph is the intersection of all these shaded half-planes plus
the boundaries of this intersection.
