A proportional relationship is also known as a direct variation

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
`y/x=k` or
`y=kx`

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In a proportional relationship

If the variable x increases -------> the variable y increases

If the variable x decreases -------> the variable y decreases
