Ответ:
The correct graph for this answer would be y=3. The image of the graph is attached to that link below. I highly recommend using the graphing calculator I used. It's called Desmos Graphing Calculator and it is my favorite. I hope this was helpful. Mark as brainliest if so. :)
P.S. I know the PDF is super inconvenient but I couldn't paste an image in the answer box.

Step-by-step explanation:
Let the number of non-fiction books be x .
Then the number of fiction books=![\frac{2}{5}x](/tpl/images/1202/3352/1ffac.png)
Since, there are 56 books in the school library.
Then,![\\\Rightarrow\frac{2}{5}x+x=56](/tpl/images/1202/3352/7138e.png)
Hence, the number of non fiction books = 40
Therefore, the number of fiction books =![\frac{2}{5}40=16](/tpl/images/1202/3352/efd13.png)
