The pair of numbers used to locate a point on a grid is called coordinate points.
Ordered pair
A point.
Coordinate plane
It is a point on the coordinate grid. The grid may be the Cartesian or coordinate plane, or its equivalent in 3 or more dimensions. It could also refer to a grid where the axes are not at right angles to one another (eg isometric grid).
Coordinate graphing sounds very dramatic but it is actually just a visual method for showing relationships between numbers. The relationships are shown on a coordinate grid. A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin.
These are called coordinates.
Ordered pair (s)
Your question doesn't make sense unless this helps : (x,y) there called the coordinates
The pair of numbers are called the coordinates.

They are co-ordinates

Mention in two points how the grid system on a map helps us to locate places.
A grid with a horizontal axis and a vertical axis that intersect at a point is called a Cartesian coordinate system. The axes are perpendicular to each other and therefore form four right angles at the point at which they intersect, known as the origin.

Grid references are a way to precisely pinpoint a location on a map by using intersecting lines on a grid. The vertical lines are numbered and are called eastings, while the horizontal lines are lettered and are called northings. The intersection of a specific easting and northing provides a unique reference point on the grid to locate a particular place.
