May I have help on question 14

Answer:
y=mx+b
(6,6) (3,8)
6m+b=6
3m+b=8
6m+b-3m-b=-2
3m=-2
m = -2/3
-2+b=8
b=10
y = -2/3x+10
I choose 12.
-2/3(12)+10
=2
so put x as 12; y as 2.
Answer:
We want to add an x value we have not used before. A function has EVERY X IN A DOMAIN going to ONLY ONE Y value.
6,3,9,7 are already used for x.
so you can put in x = 8 and y = 12 as an answer. That will work and show a function. There are also other answers.
