Answer 1

To determine the domain and range of the given relation, we can look at the provided pairs of values which represent coordinates in the form (x, y).

**Given pairs:**
1. (2, -2)
2. (7, 5)
3. (-6, -1)
4. (-6, -9)

**Domain:** This is the set of all x-values from the pairs.
- From the pairs, the x-values are: 2, 7, -6, -6.
- The unique x-values (without repetition) are: 2, 7, -6.

So, the **domain** is: {2, 7, -6}.

**Range:** This is the set of all y-values from the pairs.
- From the pairs, the y-values are: -2, 5, -1, -9.
- The unique y-values (without repetition) are: -2, 5, -1, -9.

So, the **range** is: {-2, 5, -1, -9}.

In summary:
- **Domain:** {2, 7, -6}
- **Range:** {-2, 5, -1, -9}
