Answer 1

To find the point that represents the temperature change as of Wednesday, we first need to understand the context of the data provided. The problem states that on Wednesday, the average temperature had decreased by 17.6 degrees.

Considering the days of the week and the recorded temperature changes:
- On **Sunday**, the decrease recorded was **4.4 degrees**.
- On **Monday**, the total decrease recorded was **8.8 degrees**.
- On **Tuesday**, the total decrease recorded was **13.2 degrees**.
- On **Wednesday**, the total decrease recorded was **17.6 degrees**.

Now, if we interpret the day of the week as the **x-coordinate** and the temperature change as the **y-coordinate**, we assign the following points:

- Sunday: (1, -4.4)
- Monday: (2, -8.8)
- Tuesday: (3, -13.2)
- Wednesday: (4, -17.6)

For Wednesday, the average temperature change is represented by the point (4, -17.6).

So the correct response is:

**(4,−17.6)**.
