## Homework Statement

## Homework Equations

Solving for dx/dy (change in x with respect to y) I get a solution that isn't one of the answer choices.

## The Attempt at a Solution

3y^2 = 8x' + x'/x

Coordinate:

x = 1 (given)

y = 2 (solved for in original equation)

3(4) = 9x'

12/9 = dx/dy

4/3 = dx/dy (change of x with respect to y).
