**Pair of Negative Integers with Digit -7**

To find a pair of negative integers whose digit is -7, we need to understand the concept of negative integers and the properties of digits.

**Understanding Negative Integers:**
Negative integers are numbers less than zero. They are denoted with a negative sign (-) before the number. For example, -1, -2, -3, -4, etc., are negative integers.

**Properties of Digits:**
Digits are the symbols used to represent numbers. Each digit has a specific value depending on its position in the number. In base 10, the value of each digit is determined by multiplying it with the corresponding power of 10. For example, in the number 123, the digit 1 represents 100 (10^2), the digit 2 represents 20 (10^1), and the digit 3 represents 3 (10^0).

**Finding a Pair of Negative Integers with Digit -7:**
To find a pair of negative integers whose digit is -7, we need to consider the place value of the digit and the negative sign.

Let's consider a pair of negative integers: -17 and -27.

- In -17, the digit -7 is in the ones place. The value of the digit -7 in the ones place is -7 (-7 x 10^0).
- In -27, the digit -7 is also in the ones place. The value of the digit -7 in the ones place is -7 (-7 x 10^0).

Therefore, the pair of negative integers -17 and -27 fulfill the criteria of having the digit -7.
