axis

The axis is the horizontal axis in the coordinate plane, commonly representing the value of the input or independent variable.axis

The -axis is the vertical number line of the Cartesian plane.Abscissa

The abscissa is the coordinate of the ordered pair that represents a plotted point on a Cartesian plane. For the point (3, 7), 3 is the abscissa.Cartesian Plane

The Cartesian plane is a grid formed by a horizontal number line and a vertical number line that cross at the (0, 0) point, called the origin.Coordinate grid

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.Coordinate Plane

The coordinate plane is a grid formed by a horizontal number line and a vertical number line that cross at the (0, 0) point, called the origin. The coordinate plane is also called a Cartesian Plane.Coordinates

The coordinates of a point represent the point's location on the Cartesian plane. Coordinates are written in ordered pairs: .Ordered Pair

An ordered pair, , describes the location of a point on a coordinate grid.Ordinate

The ordinate is the -coordinate of the ordered pair that represents a plotted point on a Cartesian plane. For the point (3, 7), 7 is the ordinate.Origin

The origin is the point of intersection of the and axes on the Cartesian plane. The coordinates of the origin are (0, 0).### Image Attributions
