Answer 9

O.o
3rd column , 39/13 is also 3!!
so, did you notice that y/x ratio remains constant for all pairs ??
and if so, the relation is direct variation :)

Answer 10

to write a function, take y/x = k
select any entry, say first pair, y=9,x=3
and find k, which you already found out as 3
so, the function is y/x=3 or y=3x.
did you understand all this ??
