tangent of x^2+2xy-y^2+x=27,(4,7)

tangent of

x^{2} + 2 x y - y^{2} + x = 27, (4, 7)

y = \frac{23}{6} x - \frac{25}{3}

Solution steps

Find the slope of

x^{2} + 2 x y - y^{2} + x = 27 : \frac{d y}{d x} = \frac{- 2 x - 1 - 2 y}{2 ( x - y )}

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = \frac{23}{6}

Find the line with slope m=

\frac{23}{6}

and passing through

(4, 7) : y = \frac{23}{6} x - \frac{25}{3}

y = \frac{23}{6} x - \frac{25}{3}
