Question

Which of the following shaded regions represents the solution set of in equation $|x-y|\ge 1$

• A.
• B.
• C.
• D.

Answer 1

Answer: (B)

Given in equation is
$|x-y|\ge 1$
$\Rightarrow$ $1\le (x-y)$ or $(x-y)\le -1$
$\Rightarrow$ $x-y\ge 1$ or $x-y\ge 1$
which is the required solution graph.
