anonymous · Answer

I was thinking linear I even graphed it

mathmate · Answer

It is not.
Linear would have (8-2)/(3-1) the same as (14-2)/(5-1)

mathmate · Answer

Your graph probably was not to scale, or the scale too small.

anonymous · Answer

Well its not nonliear

mathmate · Answer

That is true, but you have to eliminate inverse as well, which is also non-linear.
Inverse would have the product of "x" and "y" constant, which is not the case here.
