We need to remember that when two variables are in an inverse relationship, we have that, for example:


y=(1)/(x)

In this case, we have an inverse relationship, and we have that when x = 1, y = 12.

Therefore, we have that the correct relationship is:


y=(12)/(x)

In this relationship, if we have that x = 1, then, we have that y = 12:


x=1\Rightarrow y=(12)/(1)\Rightarrow y=12

Therefore, the correct option is the second option: y = 12/x.
