Answer:

There is not enough information to answer this problem.

Explanation:

A proportional function means that if you change X, Y will change in the same proportion. And that proportion of change will remain the same no matter which two values of X you take to compare them.

But that proportion will vary from function to function.

Without knowing what the function is, it's impossible to know the value of Y for a given X... it could be anything.
