A curve passing through (3,-2) has a slope given by (x^2 + y^2)/(y^3 - 2xy). Find the equation of the curve.

2. Relevant equations

3. The attempt at a solution

My first thought was to plug in the points (3,-2) into the slope equation and plug them into the line equation (y - y1) = m(x - x1). Is that wrong? Seemed too easy for it to be a problem for differential equations..

So, I found that i could make the slope equation into an exact equation and solved for it.

I found that the answer i get is:

with c = -17

f(x,y) = x^3/3 + xy^2 - y^4/4 - 17

However that is not the equation of the curve. Is that the equation of the tangent line at (3,-2)?

I am stuck at this point, I am pretty sure I am done with 90% of the work, but I can't seem to figure out the equation of the curve from here on.
