The axis is the horizontal axis in the coordinate plane, commonly representing the value of the input or independent variable.
The -axis is the vertical number line of the Cartesian plane.
The coordinate grid is formed by a horizontal number line and a vertical number line that cross at the (0, 0) point, called the origin. The coordinate grid is also called a Cartesian Plane or coordinate plane.
The coordinates of a point represent the point's location on the Cartesian plane. Coordinates are written in ordered pairs: .
A line graph is a visual way to show how data changes over time.
An ordered pair, , describes the location of a point on a coordinate grid.
The origin is the point of intersection of the and axes on the Cartesian plane. The coordinates of the origin are (0, 0).
