Mr. hann is trying to decide how many new copies of a book to order for his students. each book weighs 6 ounces. which ordered pair is a viable solution if x represents the number of books he orders and y represents the total weight of the books, in ounces?
a. (–3, –18)
b. (–0.5, –3)
c. (0, 0)
d. (0.5, 3)

Let

x--------> the number of books

y---------> the total weight of the books in ounces

we know that

-------> this is the equation that represent the situation

The domain is all positive integers (zero included), because the number of books can not be negative or a fraction

The range is all positive numbers (zero included), because the weight can not be negative

therefore

the answer is the option C

correct answer:

b.(19,-2)
