The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8200 ft the liquid boils at 199.7F At an altitude of 4500ftthe liquid boils at 205 25°F. Write an equation giving the boiling point b of the liquid, in degrees Fahrenheit, in terms of altitude a, in feet. What is the boiling point of the liquid at 2100 ?
