The X axis represents the Horizontal, while the Y axis represents the Vertical. Your position in the plane depends on where you stand on both axes.

The first number refers to your Horizontal position, how much to the left or to the right you are located on the plane. The second number refers to your Vertical position, how much up or down you are located on the plane. In both cases, you could call the numbers on them "steps".

Let's say 3;4. That means you are located, starting from the center (0;0), 3 steps to the right and 4 steps up. As a rule, though, as long as either of the numbers is not a 0, your location will be diagonal from the center.

If there are multiple coordinates given on the same plane, by conecting them you can get lines or a variety of curves, depending on their respective positions.

Now, on a 3D plane, there would be 3 axis: X, Y, Z. And in them, IIRC, X wasn't "horizontal" per se.

Do you understand better now?
