You need to add a picture in order for others to understand what you are referring to.
X is horizontal and it always goes first and y is vertical and it always goes

What you do is plug the z value (first column) into the formula (second column), and solve for y. For instance, the first one would be y = -1-2, or -3. The x would be the x in the ordered pair, and the final ordered pair would be (-1,-3). Make sense?
