Question 1026204
Take derivative of both sides with respect to x using the chain rule:


*[tex \large \frac{1}{x-y}(1 - \frac{dy}{dx}) = y + x \frac{dy}{dx}]


(Note that xy is a product of two functions, so you have to use the product rule here)


Use some algebra to solve for dy/dx in terms of x and y. Once you have done so, plug in x = 1, y = 0.
