Question
At sea level, the boiling point of water is 212 degrees, Fahrenheit (oF). For every 500 -foot increase in elevation above sea level, the boiling point of water decreases by about 1oF. Which equation models water's boiling point y , in oF terms of , the elevation, in feet above sea level?
The correct answer is:
Boiling point of water = 212oF
For every 500 foot increase the boiling point of water decreases by 1oF.
For every 1 feet increase, the boiling point of water decreases by 
.
The boiling point = .
