Answer : (b)\; a=-b

Hint: Use variable separable method i.e. take the y terms on one side and x terms on the other.

Given : \frac{d y}{d x}=\frac{a x+g}{b y+f}

Explanation : d y(b y+f)=(a x+g) d x

\begin{aligned} &\frac{b y^{2}}{2}+f y+C_{1}=\frac{a x^{2}}{2}+g x \\ &\frac{a x^{2}}{2}-\frac{b y^{2}}{2}+g x-f y-C_{1}=0 \end{aligned}

In circle, coefficient of x^{2} = coefficient of y^{2}

\begin{aligned} &\frac{a}{2}=-\frac{b}{2} \\ &a=-b \end{aligned}
