Well, first we want to find the value of the derivative of y. So you would take the derivative of -1/(x^2). Now, know that derivative of y is dy/dx, but we have dy and dx separate. So what youll need to do is rearrange your equation in which you can get dy/dx and not separate. Once you're able to do so, substitute your y = and your derivative of y = and show that it is a solution.
