Question

This is my last question I need help with.

Answer 1

Option 1

Explanation:

The formula of constant porpotionality is

`y = kx`

or

`y = (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
