• 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)

Consider a Number Line.
On a number line, the numbers to the right of a given number are always greater and numbers to its left are always smaller.

Given pairs are:
(3, 7), (0, -4), (1, -10), (-4, -8), (2, 5) 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).
