What is the x-value in coordinate geometry referred to as?

In coordinate geometry, the x-value is referred to as "Easting." This term is used within a Cartesian coordinate system, particularly in the context of geographic and surveying applications. The easting represents the distance eastward from a designated meridian or reference point, typically in a grid system such as the Universal Transverse Mercator (UTM), where coordinates are expressed in terms of eastings (x) and northings (y).

This is significant as easting allows surveyors and mapmakers to specify locations on a two-dimensional plane, facilitating accurate measurements and navigation. Understanding easting is crucial for interpreting coordinate data and applying it effectively in practical surveying scenarios.

In contrast, northing refers to the y-value in the coordinate system, elevation pertains to the height above a reference datum, and dip typically relates to the inclination of geological strata, making them distinct from the concept of easting.
