To explain the location of the red dot, you simply describe it by its coordinates.
<h3>Coordinates</h3>
The coordinate of a point is the location of the point in a coordinate plane or 2D plane
From the given diagram, the coordinate of the red dot is:

This means that, the red dot is located at a coordinate point of (4,3)
Hence, the location of the red dot is simply its coordinates
