The price of a personal pizza, \( y \), can be expressed in terms of the number of toppings, \( x \), using the starting price for the plain cheese pizza and the cost of each additional topping.

Starting price for plain cheese pizza: $7
Cost of each topping: $2

The equation representing the total price, \( y \), based on the number of toppings, \( x \), is:

\[ y = 7 + 2x \]
