Given is = x and y vary inversely ; this means when x increases y decreases and when y increases x decreases but the product remains unchanged.

It can be written as =
x=(1)/(y)

Now, the given values are :

x = 2 and y = 7

So, the correct answer is option B.


y=(14)/(x) or x*y=14

Hence, option B is correct.
