Nethan made eight rose bouquets and six daffodil bouquets. nethan only has enough flowers to make at most 20 rose or daffodil bouquets total. let x represent the number of more rose bouquets and y represent the number of more daffodil bouquets that nethan can make. which of the following graphs best represents the relationship between x and y?

I found the graph choices: 

Given:
8 rose bouquets
6 daffodil bouquets
total of 14 bouquets

enough flowers left to make maximum of 20 bouquets. 

x = additional rose bouquets
y = additional daffodil bouquets

20 maximum bouquets - 14 made bouquets = 6 additional bouquets

x + y = 6

y = 6 - x
x = 6 - y

If x = 0 then y = 6 
If x = 6 then y = 0
If x = 4 then y = 2
If x = 2 then y = 4

Pls. see attachment for the correct graph.
