So here's my problem, I'm having trouble starting out:

Solve the separable differential equation:

$\displaystyle 9x-5y\sqrt{x^2+1}\frac{dy}{dx}=0$

Subject to the initial condition:$\displaystyle y(0)=2$

So I have this to start out with.

$\displaystyle -5y dy=-9x+\frac{1}{\sqrt{x^2+1}} dx$

Am I headed in the right direction? Any help is greatly appreciated!
