Calculus 3

On a particular day, a scientist recorded the air temperature at 8 different heights above sea level. The scatter diagram shows the air temperature, y°C, at each of these heights, x km, above sea level. Air temperature at different heights above sea level. Height above sea level (km). (a) Using the scatter diagram, write down the air temperature recorded at a height of 2.5 km above sea level. (b) Describe the correlation between the air temperature and the height above sea level. (c) Find an estimate for the height above sea level when the air temperature is 0°C.
