The points show the relationship between water temperatures and surface air temperatures.
Complete the table of values:
| Water Temperature (°C) | $-3$−3 | $-2$−2 | $-1$−1 | $0$0 | $1$1 | $2$2 | $3$3 |
|---|---|---|---|---|---|---|---|
| Surface Air Temperature (°C) | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ |
