The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8100 ft, the liquid boils at 198.61°F. At an altitude of 4500 ft, the liquid boils at 205.45°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 2400 ft?
Write an equation.
b=
