8, and 5 in the domine of paired in 4 in the range.
Then X, Y coordinates relation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=9d23bc9bf2e9f463c619066c8d971b4f.png\")
.
Inverse relation: Exchange x and y in each ordered pair to write the inverse relation.
