How do you change a temperature that is in Fahrenheit to Celsius form?

Question

amistre64 · Answer

we can create a function; that has already been created :)  by knowing that 0 = 32  and 100= 212

amistre64 · Answer

the slope between then and the points give us a formula to follow

amistre64 · Answer

F,C
----
212,100
- 32, 0
--------
180,100;    slope = y,x = 100/180 = 10/18 - 5/9

C-0 = 5/9(F - 32)

C = (5/9)F - 160/32

C = (5/9)F - 5  i believe

amistre64 · Answer

100 = 5/9(212) - 5 should work if i did it right

i think it should be -32 and not -5 tho....

amistre64 · Answer

160/32  is where i missed it ; thats a typo

Thanks

amistre64 · Answer

i looked it up and it says:

C = 5/9(F-32) ; i shoulda stopped while I was ahead lol

amistre64 · Answer

at f = 212 that sould be c - 100 then

212
-32
----
180(5)
------ = 100 all right :)
