I've seen them referred to as "integer degree intersections".

The exact position of a place derived from mathematical coordinates on the Earth's grid is the absolute location. The absolute location would be the latitude and longitude of a location.

The number are called coordinates.
An ordered pair gives coordinates and location
That is called the coordinates of the place.
Oddly enough, they are called the coordinates!
Any city or geographic location can be used as coordinates if you take the compass bearing of them. The reciprocal of those bearings could then be used to find your present location by a method called triangulation.

Three coordinates suffice to define a location in space. On a surface only two coordinates are required.

A centroid is a location. A location cannot be positive nor negative! One or both coordinates can be negative. Or more coordinates in higher dimensions.
If you are talking about the things in the perentheses, (5,-9), they are called ordered pairs. Ordered pairs help you find a location on a coordinate graph.
