If I read that the right way, the only one that remotely would fit the equation would be #2. So the answer is b

For now , just ignore the constant 5/9 *32

c = 5/9 f when f changes 1 c changes 5/9 so A is true

when f changes 5/9 c changes 25/81... not 1 so C is untrue

(as an aside when f changes 9/5 c changes 1 )

re-arrange

9/5c = f when c changes 1 f changes 9/5 or 1.8 so B is true

D) I and II only
