Barometric pressure is a linear function of altitude. The barometric pressure is 598 millimeters of mercury at an altitude of 1.8 kilometers. The pressure is 577 millimeters of mercury at 2.1 kilometers.a. Write a formula for the barometric pressure as a function of the altitude.b. What is the altitude of the pressure is 657 millimeters of mercury? (you will get credit if you just set this equation up correctly without solving)
