$y = xy^2 + 4y^3 + 3x = 0$ at the point (1,-1)
To start I did the sum rule, separated all the terms, and got their derivatives
Then I expanded and substituted the point in and then used that slope to find the equation of the tangent line in point slope form
First, I was wondering if I did this correctly? Second, what is the slope of the tangent line?
