Question

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

Answer 1

well, they give you 2 points for reference :)

Answer 2

32,0 and 212,100

determine the slope between them and calibrate it

Answer 3

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

Solve and simplify for a and b

Answer 4

100/180 is the slope; 5/9

5/9F -(5(9)/9) + 100

C = (5/9)F +100 maybe?

Answer 5

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

Answer 6

that would work too

Answer 7

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