In a coordinates system, where is longitude represented?

Longitude is typically represented in a coordinate system as the "x" position. In the context of geographical coordinates, longitude indicates the east-west position of a point on the Earth's surface while latitude corresponds to the north-south position.

In a Cartesian coordinate system, the x-axis usually represents horizontal measurements, which align with how longitude is defined in the real world. Longitude lines run from the North Pole to the South Pole and are used to measure distances east and west from the Prime Meridian. Thus, the correct representation of longitude in this system is indeed as an "x" coordinate.

Understanding this helps clarify geographic position within a two-dimensional space and is powerful for various applications, including navigation and mapping.
