Coordinate Plane Concepts

Front

Coordinate plane

Back

A two-dimensional grid formed by the intersection of two perpendicular number lines, called the x-axis (horizontal) and the y-axis (vertical), where points are located using ordered pairs based on their position relative to the origin (0, 0) on the plane.

Front

X-Axis

Back

The principal line or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates.

Front

Y-axis

Back

The vertical axis of a system of coordinates. All points on this line have an x value of zero.

Front

Origin

Back

The point where the x-axis and y-axis intersect, denoted as (0, 0).

Front

Ordered pairs

Back

Each point on the coordinate plane is identified by an ordered pair of numbers, where the first number represents the x-coordinate and the second number represents the y-coordinate.

Front

Quadrants

Back

The coordinate plane is divided into four sections called quadrants, numbered counterclockwise from the top right.

Front

Line

Back

A series of points on a plane that creates a straight two-dimensional form that extends in two directions forever.

Front

Line segment

Back

The shortest distance between two specified points on a plane.

Front

Slope (on a graph)

Back

The steepness of a line, measured by the ratio of the vertical change (rise) between two points on the line divided by the horizontal change (run) between those same two points.

Front

Positive slope

Back

Line goes upwards from left to right.
