Question

Y is directly proportional to x. Create an equation using k as the constant of proportionality.

Answer 1

`y = kx`

Explanation:

y is directly proportional to x.

`y \propto x`

`y = kx`

Where k is as the constant of proportionality.

Answer 2

y = kx

Explanation:

Y is directly proportional to x which means that

=> y ∝ x

=> y = kx

Where k is the constant of proportionality.
