Differentiate each function by applying the basic rules of differentiation
`(ax-b)/(cx-d)`

Explanation

To differentiate the function \( y = \frac{ax - b}{cx - d} \), we will use the quotient rule of differentiation. The quotient rule states that if you have a function \( y = \frac{u}{v} \), where both \( u \) and \( v \) are functions of \( x \), then the derivative \( \frac{dy}{dx} \) is given by:

\[ \frac{dy}{dx} = \frac{v \frac{du}{dx} - u \frac{dv}{dx}}{v^2} \]

Here, we identify:
- \( u = ax - b \)
