A) \[y=\sqrt{x\frac{dy}{dx}}\]
B) \[\frac{dy}{dx}=y+x\]
C) \[\frac{dy}{dx}=\frac{y}{x}\]
D) None of these
Correct Answer: C
Solution :
The equation of all straight lines passing through the origin is \[y=mx\] .?.(i) where m is arbitrary constant Differentiate (i) w.r.t. x, we get \[\frac{dy}{dx}=m\] Þ \[\frac{dy}{dx}=\frac{y}{x}\], (By (i)).
