Graph Decimals on Coordinate Plane

Definition: A set of values that show an exact position.

On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down.

• Y- Axis

• X- Axis

• Integer

• Coordinate

Definition: The plane formed by a horizontal axis and a vertical axis, often labeled the x-axis and y-axis, respectively.

• X- Axis

• Y- Axis

• Inequality

• Coordinate Plane

Definition: Two numbers written in a certain order.

Usually written in parentheses like this:

(12,5)
