• B. (3, 7), (-4, -8) and (1, -10)
• C. (0, -4), (-4, -8) and (1, -10)
• D. (0, -4), (-4, -8) and (3, 7)

Answer 1

The correct option is C

(0, -4), (-4, -8) and (1, -10)

Here, a number to be on the right of another number on number line means that the first number is greater than the second number.
Given pairs are:- (3, 7), (0, -4), (2, 5), (-4, -8), (1, -10), and (-1, 3).
Here, $3<7$, $0>-4$, $2<5$, $-4>-8$, $1>-10$ and $-1<3$.
So, the required pairs are (0, -4), (-4, -8) and (1, -10).
