Which table of values is a linear relationship? Write an equation for the relationship.

x|5 10 15 20 25 30

y|20 30 40 50 50 50

I want to say that x is but I have no theory as to why. I have looked at sample problems in the text and still do not understand how to do this. Any help would be appreciated!!
