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). |
