Key Concepts

Cartesian Coordinate System

The Cartesian coordinate system is a method of defining points on a plane using ordered pairs of numbers, usually written as (x, y). This system involves two perpendicular axes: the horizontal x-axis and the vertical y-axis, which intersect at the origin, providing a reference framework for locating any point in the plane.

Coordinate Determination

Coordinate determination involves identifying the horizontal (x-coordinate) and vertical (y-coordinate) distances from the origin to a point. These distances are measured relative to the axes, and their signs indicate the direction along each axis. This process allows for accurate placement of points based on given spatial relations.

Axis and Sign Conventions

Axis and sign conventions refer to the rules for assigning positive or negative values based on a point’s position relative to the origin. Generally, points to the right of the y-axis have positive x-values, while points to the left have negative x-values; similarly, points above the x-axis have positive y-values, and those below have negative y-values. These conventions are essential for correctly interpreting and plotting coordinates on a Cartesian plane.
