A table of values is a chart that helps to organize and visualize information. It is frequently used to show the relation between two variables.

In the table above, each $x\text{-}$ and $y\text{-}$values appearing in the same row comprise an ordered pair. For example, the $x\text{-}$value $2$ corresponds to the $y\text{-}$value $6$. This is usually represented with the notation $(2,6).$
