Answer:
Step-by-step explanation:
<u>Concept</u> : 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} ,
