Question:

Consider the inequalities x > y and x + y ≤ 3 where y ≤ 1. The feasible region is:

Options:

unbounded region containing the origin

open half plane containing the point (0, 3)

open half plane containing the point (2, 1)

bounded region containing (3, 0) but not the origin

Correct Answer:

open half plane containing the point (2, 1)

Explanation:

Given inequalities

$x>y$

$x+y\le3$

$y\le1$

Check origin $(0,0)$

$0>0$ is false

So origin is not in region

Check point $(0,3)$

$y=3\le1$ is false

So not in region

Check point $(2,1)$

$2>1$ true

$2+1=3\le3$ true

$1\le1$ true

So $(2,1)$ lies in region

Since $x>y$ is strict inequality, region is open

Also region is not bounded

Correct answer: open half plane containing the point $(2,1)$
