The first element in a coordinate pair. When graphed in the coordinate plane, it is the distance from the y-axis. Frequently called the x coordinate.

A term in rectangular coordinates referring to the horizontal distance of any point from the vertical axis.

The value representing the distance of a point from the Y-axis in the Cartesian coordinate system, measured along a line parallel to the X-axis. (Compare "Ordinate".)

The x-coordinate in a point (x,y). For the point the abscissa is . See ordinate.

the value of a coordinate on the horizontal axis

The abscissa is the x-coordinate of an ordered pair.

The -coordinate, or first coordinate of an ordered pair.

The x-coordinate. In the point (6,3), the abscissa is 6.

This is the X coordinate on a Cartesian graph. The Cartesian system is the one that looks like a grid full of squares.

the coordinate of a point in a plane Cartesian coordinate system obtained by measuring parallel to the x-axis ("the 'x' value").

The horizontal line of a graph. This is also referred to as the x-axis.

The abscissa is the x-axis of a coordinate system. The numerical value of the abscissa tells you the distance from the origin along the x-axis. The abscissa is the first number, x, in the coordinates of a point (x,y).|-3|=3

The horizontal axis. Usually the independent variable is plotted on the abscissa. See ordinate.

the horizontal axis (x-axis) of a graph or plot: "The year is shown on the abscissa, while the rainfall is shown on the ordinate (y-axis)".
