Find the tangent line equation for the following at (-2,-2):

OpenStudy (anonymous):

\[4x^2+2y^2-10=3xy-x\]

OpenStudy (anonymous):

I tried solving this out and I got the following: \[\frac{ dy }{ dx } = \frac{ 8x - 3y }{ 3x + 4y } + 1\]

OpenStudy (anonymous):

I'm not sure if I skipped a step or just didn't derive everything properly.

OpenStudy (anonymous):

Answer choices are: a) -2x - 9y = 22 b) 9x + 2y = -22 c) 9x + 2y = 12 d) 2x - 9y = 14 e) -9x + 2y = -22

OpenStudy (danjs):

8x + 4*y*y' = 3x*y' + 3y - 1 (3x - 4y)* y' = 8x - 3y + 1 \[y' = \frac{ 8x - 3y +1 }{ 3x - 4y }\]

OpenStudy (danjs):

slope -9/2 at point (-2,-2)

OpenStudy (anonymous):

and having the slope and a point you can derive the line equation.
