Question 587243
What is the slope of the line tangent to the curve 3y^2-2x^2=6-2xy at the point (3,2)?
------------
3y^2-2x^2=6-2xy
6ydy - 4xdx = -2(xdy + ydx) = -2xdy - 2ydx
6ydy + 2ydy = -2ydx + 4xdx
4ydy = (2x - y)dx
dy/dx = (2x - y)/4y
----------------------
f'(3,2) = (6 - 2)/(4*2) = 1/2
Tangent line:  2y = x + 1
