Key Concepts

Quadrants

The coordinate plane is divided into four regions called quadrants, each defined by the sign of its x and y coordinates. Recognizing which quadrant a point falls into helps determine the signs of its coordinates, such as knowing that points in the lower half of the plane have negative y-coordinates.

Negative Values

In the context of the coordinate plane, negative values in a coordinate (such as the y-coordinate) indicate a position below the x-axis. Understanding negative values is essential to determine the location of points in different regions of the plane, particularly when identifying regions like quadrants where one coordinate is negative.

Cartesian Coordinates

Cartesian coordinates are the pairs of numbers (x, y) that denote the position of a point on the coordinate plane. The x-coordinate represents the horizontal distance from the origin, while the y-coordinate represents the vertical distance, allowing each point to be uniquely identified by its distance along each axis.

Coordinate Plane

The coordinate plane is a two-dimensional surface defined by a horizontal axis (x-axis) and a vertical axis (y-axis), which intersect at a point called the origin. It provides a systematic way to describe locations on the plane using pairs of numbers, allowing for precise plotting and analysis of points and shapes.

Y-Coordinate

The y-coordinate of a point indicates its position relative to the horizontal x-axis on the coordinate plane. This value determines whether the point lies above or below the x-axis, with positive values indicating points above and negative values indicating points below the axis.
