The equation relating the cost \( y \) in dollars to the number of pizzas \( x \) is given as \( y = 4.5x \).
In this equation, the coefficient of \( x \) (which is 4.5) represents the cost per pizza. Therefore, the unit rate is:
\[
\text{Unit Rate} = 4.5 \text{ dollars per pizza}
\]
So the correct answer is **$4.5 / pizza**.
