Remember starts at zero slope is up 4 right 1
Y= 4/1x+0
Y=4x
        
                    
             
        
        
        
The answer should be 
Y=-3x+19

There is 20x more nonfiction than fiction so you do
20+1=21
so then to find out what 

 of 1155 is we do
1155÷21=55
so then we times 55 by 20 because there are 20x more nonfiction than fiction
55x20=1100
soo now we know there is 
1100 nonfiction books and 
55 fiction books 
to check whether we are right we can do
1100=55=1155
we are right because there is 1155 books in the library
hope i helped
