Relation

Can you help describe this relation as an equation and in words given the co-ordinates: (-3,-5),(-2,-3),(-1,-1),(0,1),(1,3),2,5,(3,7). Thanks in advance.

Re: Relation

Well, it looks like the second number increases by 2 when the first number increases by 1. And when the first number is 0, the second is 1.
That's enough information to write an equation of a LINE.
