Two important reference points for temperature are the boiling point and the freezing point of water. water freezes at 0degreesC or 32degreesF. Water boils at 100degreesC or 212degreesF.
--------
You have two points relating Fahrenheit to Celcius (F,C)
(32,0) and (212,100)
slope = 100/(212-32) = 100/180 = 5/9
Then 0=(5/9)32+b
b= -160/9
Celcius = (5/9)(Fahrenheit)-160/9
or
Farenheit = (9/5)(Celcius) +32
--------
