Pairs of points are $\"\"$

Plot the order of pairs on coordinate plane. $\"\"$ $\"\"$

The relation is $\"\"$

The domain of the relation is the set of all first (x-coordinates) coordinates.

The domain of the relation is: $\"\"$

The range of the relation is the set of second (y-coordinates) coordinates.

The range of the relation is $\"\"$

Draw the vertical lines through the points. Observe that one vertical line passing through all points. This graph fails the vertical line test. Therefore the relation is not a function.
