Question

Please answer.
Graph the feasible region for each set of constraints.
1.) {x+y<(or equal to)9
2x-y<(or equal to)5
x>(or equal to)0, y>(or equal to)0

Answer 1

Solve each of the first 2 equations for y. The sign will stay facing in the same direction, unless you multiply or divide by a negative number. If the end result is y ≤ mx + b, shade the area below the graph. If it's y ≥ mx + b, shade the area above it.
The feasible region is the area that is shaded by all the functions.
