At the beach in San Francisco (0 meters) the pressure of the atmosphere is 101.325 kPa (kilopascals) and in Denver, 1609.344 meters above sea level, the pressure of the atmosphere is about 83.437 kPa. Using this data, find a linear equation for pressure P in terms of altitude h. (Hint: write the pressure and altitude in each location as a point (h, P). Then use the point-slope form to find the equation of the line.)
