The relationship between altitude and the boiling point of a liquid is linear. At an altitude of ​8400ft, the liquid boils at 199.04F. At an altitude of ​4300ft, the liquid boils at 206.83F. 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 ​2600ft?
