From the listed choices, you can prove the series diverges using either the integral or <em>p</em>-series test.
We have

which diverges to infinity, so the series is divergent.
The series

converges only for
. In the given sum, we have
, so the series is divergent.

Answer:
Assume x is directly proportional to y :

when y is 9, x is 2:
substitute to find value of k :

Therefore, equation is:
