Which of the following is true about −9?(1 point)

It is an integer but not a whole number.

The correct answer is: It is both an integer and a whole number.

To determine the truth about −9, we need to understand the definitions of integers and whole numbers.

Integers are numbers that can be positive, negative, or zero, without any fractions or decimals. Whole numbers, on the other hand, are the numbers 0, 1, 2, 3, and so on, including all positive integers.

In this case, −9 is a negative number without any fractions or decimals, so it fits the definition of an integer. It is not a positive number.

As for whole numbers, they include 0 and all positive integers. Since −9 is a negative number and not zero, it does not fit the definition of a whole number.

Based on the definitions, the correct response would be: It is an integer but not a whole number.
