identify the function

Can someone please help me with this problem.

identify the function from this data chart:

X Y
2 6
4 12
6 18
8 24


its mulitple choice and here are the four choices: y=x/3 y=x+4 x=3/y x=y/3
I just cant seem to get started with this one. I dont understand how to even start solving this. can someone help me with the principles and help me understand what I must do first with this?

You have choices? Have you considered substituting?

2/3 is not 16. Forget that.

2 + 4 is not 16. Forget that.

3/16 is not 2. Forget that.

16/3 is not 2. Forget that.

It appears that you need some better choices.

OR, you can fix the problem statement and try again. Perhaps that first point should be (2,6)?

I corrected it. The first pair was 2,6.
And thanks. I did need to substitute. I thought that was it but I just got a brain freeze. thanks again.
