The function y = 30x describes the total number of pencils, y, that the principal should order for x students. Which set of terms best describes the function y = 30x in this scenario?

a.continuous and non-linear
b.discrete and non-linear
c.discrete and linear
d.continuous and linear

D) continuous and linear.
the statement y=30x is a linear (directly proportional) statement which is continuous over the interval [-infinity,infinity]
the answer will be directly related (linearly) to the number of students for which pencils are being purchased
