It is an integer but not a rational number. It is an integer but not a whole number. It is an integer but not a whole number. It is both an int

Answer 1

The correct statement about \(-9\) is:

**It is an integer but not a whole number.**

Here's the reasoning:
- Whole numbers are non-negative integers (0, 1, 2, 3, ...), so \(-9\) does not qualify as a whole number.
- Integers include all whole numbers and their negative counterparts, so \(-9\) is indeed an integer.
- Additionally, \(-9\) is a rational number because it can be expressed as \(-9/1\).

Thus, the most accurate description based on the provided options is that \(-9\) is an integer but not a whole number.
