Implicit Differentiation - Calculus

 Need to find slope of tangent line to curve 5(x^2 + y^2)^2 = 169(x^2-y^2) at point (3,-2) . It is implicit differentiation but I keep getting the wrong value at 3,-2. I'm not sure if I am isolating the y' correctly. Anyone want to take a shot?

What value do you get for the slope, and what is the correct answer?

Quite sure. No polar form yet, just implicit differentiation. Someone asked about right answer , not sure just know mine are wrong (online hwk grading)

Here is proof that -1/8 is the correct answer, https://www.desmos.com/calculator/zvyelnx2rm although Wyzant might disapprove this comment because it contains a link:
