Question

If we are creating a function of money paid for pizza and the number of pizzas received, where x is the cost and y is the pizzas received, which of these are viable solutions?(4 points)
Viable Not Viable
(20,3)


(30,-4)


(-2,4)


(0,0)

Answer 1

Viable: (20, 3) and (0, 0)

Not viable: (30, −4) and (−2, 4)

Reason: You cannot receive a negative number of pizzas, and you normally cannot pay a negative amount of money, so both coordinates must be ≥ 0.
