The distance between them is the absolute value of the difference in their vertical coordinates.
Subtract the y-coordinates of the points and take the absolute value
absolute value verctor
The x coordinates are horizontal whereas the y coordinates are vertical on the Cartesian plane.

Vertical.
The distance between them is the absolute value of the difference in their vertical coordinates.
Subtract the y-coordinates of the points and take the absolute value
The difference in the y coordinates would be your vertical separation.
The vertical distance of the aircraft above the surface.
The absolute difference in the vertical direction is zero but the absolute difference in the horizontal direction will be the horizontal distance - which is the distance between the points.
absolute value verctor
An absolute altimeter is an instrument which measures vertical distance to the surface below a certain reference point.
In 2-dimensional space, it is the difference between their y-coordinates, in 3-dimensional space, it is the difference between their z-coordinates.
A vertical shift is the vertical motion of a function on a graph through manipulation of the y-coordinates, while simultaneously leaving the x-coordinates unchanged. A horizontal shift is the opposite of a vertical shift, in that the function is moving horizontally by manipulating the x-coordinates and leaving the y-coordinates unchanged.
The coordinate plane in 2-dimensional space has one point which is the origin. This point is usually denoted by the letter O and has coordinates (0, 0). There are usually two mutually perpendicular axes - one horizontal and one vertical. The first coordinate of any point is the distance of the point, in the horizontal direction, from the vertical axis. The second is its distance, in the vertical direction, from the horizontal axis. In space with 3 or more dimensions the coordinates are defined in an analogous manner.
