Write the relation π
for the following diagram, where set π contains the numbers six, 10, and 11 and set π contains the numbers eight, 12, 13, and 28.

A relation π
from π to π is a set of ordered pairs π, π, where π exists in set π and π exists in set π. Each arrow in the diagram represents an ordered pair in the relation π
. The arrow from six to eight means that six, eight exists in the set π
.

Likewise, the arrow from 10 to 12 shows that the ordered pair 10, 12 exists in π
. And finally, the arrow from 11 to 13 shows that the ordered pair 11, 13 exists in π
. Therefore, π
contains the three ordered pairs or coordinates: six, eight; 10, 12; and 11, 13.
