Question

Using implicit differentiation:
Find the equation of the tangent line at the given point on the curve.
2xy - 2x + y = -14 (2, -2)

Answer 1

well, show me what you have tried so far

Answer 2

there are no difference in the derivative rules from explicit to implicit; if you need to rewrite y as a funcion of x to see the chain rule applications, then dont be afraid to do so

2x f(x) - 2x + f(x) = -14
