| Money Constraint:
For this constraint we need to graph its constraint-boundary line. The equation for this line is .
We graph this line by finding where it intercepts the two axes, and then
drawing a line through these two intercept points. |
|||
| To determine which side of the constraint boundary line is the feasible
side, we check the origin (0, 0). If
and ,
then . |

| Since (0, 0) satisfies the money constraint, the feasible side of the constraint boundary line is the side containing the origin, as shown by the shaded region in the graph. | |||
