Coordinate Plane Basics

Front

Coordinate

Back

One of two numbers in an ordered pair that tells the location of a point. The first coordinate tells the direction and distance along the x-axis. The second coordinate tells the direction and distance along the y-axis.

Front

Coordinate plane

Back

A plane with an x-axis and a y-axis. Using the numbers on the axes, you can give the exact location of a point.

Front

Ordered pair

Back

A pair of numbers in parentheses that names the location of a point on a coordinate plane. The first number is the x-value, and the second number is the y-value.

Front

Origin

Back

The point where the axes intersect on a coordinate plane. The coordinates of the origin are (0, 0).

Front

X-axis

Back

The horizontal number line on the coordinate plane.

Front

Y-axis

Back

The vertical number line on the coordinate plane.

Front

X-coordinate

Back

The first coordinate in an ordered pair. The x-coordinate of a point tells its distance to the right or left of the origin on a coordinate plane.

Front

Y-coordinate

Back

The second coordinate in an ordered pair. The y-coordinate of a point tells its distance above or below the origin on a coordinate plane.
