Answer 1

The correct response is: It is an integer but not a whole number.

Explanation:

• A whole number is a non-negative integer (0, 1, 2, 3, ...), while integers include both negative and positive whole numbers, as well as zero (… -3, -2, -1, 0, 1, 2, 3 ...).
• Since -9 is a negative number, it is an integer but not a whole number.

So, the accurate answer is that -9 is an integer but not a whole number.
