Best ResponseYou've already chosen the best response.0Use some implicit differentiation, differentiate the function, solve for dy/dx and plug in the points (2,4). Then, just use yy1=m(xx1) to find the tangent line.

Best ResponseYou've already chosen the best response.0I'm getting this: \[2x  4x*\frac{dy}{dx}  4y  6y^2\frac{dy}{dx} = 0\]\[2x4y = 4x \frac{dy}{dx} + 6y^2\frac{dy}{dx}\]\[\frac{dy}{dx} = \frac{2x4y}{4x+6y^2}.\]
