,The owner of Grizzly Tea Shack is thinking about adding iced tea to the menu. He thinks he can do this with minimal effort by adding ice cubes to cups of hot tea. He decides to measure how changing the number of ice cubes in a glass of freshly brewed tea affects its cooling rate.
To begin, the owner varies the number of ice cubes, x, he puts in glasses of freshly brewed tea. He then checks the temperature (in Celsius), y, of each glass after 10 minutes.
| Ice cubes | Temperature after 10 minutes (in degrees Celsius) |
| 1 | 17 |
| 1 | 16 |
| 3 | 9 |
| 4 | 12 |
| 4 | 7 |
Round your answer to the nearest thousandth.
