Solution

The correct option is B Not proportional to x
Expanding the given equation, we get
$x y + 4 x = 1$
$Here, x y = 1 - 4 x, which is not a constant$ . Similarly,
$\frac{x}{y} = (\frac{1}{4 y} - \frac{x}{4}), which is not a constant$ .
$So, y is not proportional to x .$

In the equation x(y+4)=1, y is

The correct option is B Not proportional to xExpanding the given equation, we get xy+4x=1 Here, xy=1−4x,which is not a constant. Similarly, xy=(14y−x4),which is not a constant. So, y is not proportional to x.
