Question

The shaded region in the figure shown represents the solution set of

• A. $x-y\ge 0$, $x+y\le 0$
• B. $x-y<0$, $x+y<0$
• C. $x-y\ge 0$, $x+y\ge 0$
• D. $x-y\le 0$, $x+y\ge 0$

Answer 1

The correct option is C $x-y\ge 0$, $x+y\ge 0$

The shaded region represents $x-y\ge 0$
$x+y\ge 0$
$\therefore$ (3) is correct.
