Answer 1

The correct statement about −9 is:

It is an integer but not a whole number.

An integer includes both positive and negative whole numbers, whereas whole numbers only include non-negative integers (0 and positive integers). Therefore, while −9 is an integer, it does not qualify as a whole number.
