Q.The solution of $\dfrac{dy}{dx} = \dfrac{ax + by + c}{dx + ey + f}$ (linear) is obtained by substituting

x = X + h

y = Y + k

where

h,k

solve

ah + bk + c = 0

dh + ek + f = 0

x = X + h

y = Y + k

where

h,k

solve

ah + bk = c

dh + ek = f

x = X - h

y = Y - k

none

The correct solution involves applying the fundamental concept to derive the final value step by step...
