Consider the objective function
$Z=x-y$
subject to the constraints:
$\begin{aligned} & x+2 y \leq 10 \\ & x+y \geq 2 \\ & x \geq 0, y \geq 0\end{aligned}$
What is the minimum value of $Z$ subject to the above constraints?

• Correct answer
  A

  $-5$
• B

  $-2$
• C

  $2$
• D

  $-10$

Hence, the correct answer is option: 'A'.
