Answer 2

15

Explanation:

Given that Jared is taking inventory of the books in his school library.

A graph given is a straight line starting from (0,0) passing through points as (1,15) (2,30)...

This implies that on x axis number of shelves and y axis no of books are marked

So for 1 shelf we have 15 books.

Thus constant of proportionality in terms of number of books per shelf is ___.15
