Question

The cheese pizza at my favorite restaurant costs $10.75 for a large pizza. It then costs $1.50 for every topping added. I can represent this relationship as a linear equation. The y-intercept is...

Answer 1

10.75

Explanation:

Let the number of toppings be x.

Let the total cost of the pizza be y.

Each topping costs $1.50, so the cost from the toppings is 1.50x.

The fixed cost is the price of the pizza, $10.75.

The total cost is the fixed cost of the pizza plus the cost of the toppings.

y = 10.75 + 1.5x

y = 1.5x + 10.75

Now the equation is in the y = mx + b form, so you see that the y-intercept, b, is 10.75.

Answer: 10.75
