A weather balloon was launched for weather forecast. At an elevation of 1,000 meters above the sea level, the outside temperature recorded 12°C.

As the balloon went up, the outside temperature decreased linearly. At an elevation of 1,500 meters above the sea level, outside temperature recorded 8.6°C. If the temperature decreased at a constant rate as the balloon went up, which of the following models best describes temperature C at an elevation h meters above the sea level?
