Answer:

Option 1

Step-by-step explanation:

The formula of constant porpotionality is

y = kx

or

y =  \frac{k}{x}

where k is the constant of porpotionality.

This equation is direct variation so we will use

y = kx

The equation is in the form

y = 1.5x

1.5 is in k place so the constant of porpotionality is 1.5
