x + y = xy
1 + dy / dx = y + x(dy / dx)
dy / dx = (y – 1) / (1 – x)

the respond is c, you ought to use implicit differentiation. The product rule is used on the right hand area and then algebra will enable factoring dy/dx. remember the spinoff of y with admire to x is dy/dx. The spinoff of x with admire to x is a million.

1+y´= y+xy´s0 y´=(1y)/(x1)

1+dy/dx=y+x(dy/dx)
dy/dxx(dy/dx)=y1
dy/dx(1x)=y1
dy/dx=(y1)/(1x)
