Question

State True or False.
Consider the equation x(y + 1) = x + 3 . Hence x is directly proportional to y.

• A. True
• B. False

Answer 1

The correct option is B False

We know that the condition for direct proportion is
$\frac{x}{y}=constant$
and the condition for inverse proportion is xy = constant

Expanding the given equation we have,
xy + x = x + 3
xy = 3
So, x is inversely proportional to y.
