Water freezes at 0 degrees celcius and 32 degrees fahrenheit water boils at 100 degrees celcius and 212 degrees fahrenheit, write celsius as a linear function of degrees fahrenheit

Question

amistre64 · Answer

well, they give you 2 points for reference :)

amistre64 · Answer

32,0 and  212,100

determine the slope between them and calibrate it

anonymous · Answer

Let C = aF+b
So 0=32a+b
and 100 = 212a+b

Solve and simplify for a and b

amistre64 · Answer

100/180 is the slope; 5/9

5/9F -(5(9)/9) + 100

C = (5/9)F +100  maybe?

anonymous · Answer

should i do y1-y2/x1-x2=slope

amistre64 · Answer

that would work too

amistre64 · Answer

100 - 0
------- = slope  yep
212 - 32
