Too many separate questions in one posting.

(1) F and C temperatures

Identify two points and create the formula.
Points (F,C) are (32,0) and (212,100).

in point-slope form

slope-intercept form, which you might approximate as .
That is formula for Celsius as function of Fahrenheit.

If you want F as a function of C, then just solve the equation for F.

(2) and (3)
You do those on your own.

This is conversion, not really a math problem.
------
C = 5(F - 32)/9
F = 1.8C + 32
-----------
To convert from C to F:
Multiply by 9 and add 160, then double it.
Move the decimal point 1 to the right.
eg:
37C = (9*37 + 160)*2 = 493*2/10 = 98.6F
You can do that "in your head."
