 x2+xy+y2=9 @ (1,2)x^2+xy+y^2=9\ @\ \left(1,2\right)  Use implicit differentiation to write the equation of the tangent line to the curve at the given point.      

 y−1=−45(x−2)y-1=\frac{-4}{5}\left(x-2\right)  

 y−2=−45(x−1)y-2=\frac{-4}{5}\left(x-1\right)  

 y−2=45(x−1)y-2=\frac{4}{5}\left(x-1\right)  

 y+2=−45(x+1)y+2=\frac{-4}{5}\left(x+1\right)
