Question

This is my last question I need help with.

Answer 1

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
