Question

Encircle the odd one of the following.

• A. $(-3,3)$
• B. $(-5,5)$
• C. $(-6,1)$
• D. $(-8,8)$

Answer 1

The correct option is C

$(-6,1)$

Adding the coordinates of each option, we get

$$\begin{gathered} \left(A\right)\Rightarrow –3+3=0 \\ \left(B\right)\Rightarrow –5+5=0 \\ \left(C\right)\Rightarrow –6+1=-5 \\ \left(D\right)\Rightarrow –8+8=0 \end{gathered}$$

Here, $\left(A\right)=\left(B\right)=\left(D\right)=0$

Hence, option (C) is the odd one.
