{{ printedBook.courseTrack.name }} {{ printedBook.name }} To graph the ordered pairs on a coordinate plane, we must recall that the first value corresponds to the horizontal axis — the $x-$axis — and the second one to the vertical axis — the $y-$axis.

Now let's determine whether the relation is a function. If the relation is a function, any given $x$-value can only have one corresponding $y$-value. However, examining the ordered pairs, we can see that two of them have the same $x$-values but different $y$-values.
$(-2,2),(2,1),(2,-4),(6,3) $
Thus, the same $x-$value is paired with two different $y-$values. This means that the relation is **not** a function.
