1. The problem statement, all variables and given/known data The slope of the line tangent to the curve y^3 + x^2y^2 - 3x^3 = 9 at (1.5,2) is approximately 2. Relevant equations Answer choices A) 0.39 B) 3.2 C) -11.45 D) -2.29 E) -3.2 3. The attempt at a solution Well, I solved for the derivative, but I'm not sure if it was to any avail seeing as when I plug the point back in I do not get an answer choice. I got: dy/dx = (-2xy^(2) + 9x^2) / (3y + 2x^(2)y) Did I solve the derivative incorrectly? Or is plugging in the point not the correct course of action? Thank you again for all your help, I've been struggling with this problem a lot and any guidance/explanation would be great!
