y varies inversely with x.


That says

when x is 3.5, y is 1.5


Plug those in:

what is the value of k, the constant of inverse variation?


Solve for k.  Multiply both sides by 3.5







That's the answer. That means that the equation



is really this



and that equation can now be used to find the value of y for 
any other value of x.
