On implicit differentiation problem.

Step-by-step explanation:

Concept : We have to differentiate the given equation twice and then put the values of x and y at the given point.

The given point is (2,-5).

Given    xy - y = -5

Differentiating both sides,

= 0

Substitute (x,y) as (2,-5)

= 0

Differentiating again, we get

Substitute values of x , y and \frac{dy}{dx} ,

ou would have 12 of each
