Key Concepts

X-Coordinate

The x-coordinate is the first component of an ordered pair and describes the horizontal position of a point in a Cartesian coordinate system. It indicates the distance and direction of the point from the vertical (y) axis, thereby determining its placement along the horizontal axis.

Ordered Pair

An ordered pair is a fundamental element in coordinate geometry, consisting of two components that represent the position of a point in a two-dimensional space. The first number represents the horizontal position (x-coordinate) and the second number represents the vertical position (y-coordinate), with the order being crucial for determining the point's exact location.
