absciss

The student calculates the absciss on the coordinate plane.

Definition

1. Noun:
   • Mathematics: "absciss" is a less common variant of "abscissa," referring to the horizontal coordinate of a point in a two-dimensional Cartesian coordinate system. It represents the distance from the point to the vertical (y) axis, measured along the horizontal (x) axis.

Usage Examples

• (The x-coordinate is 3.)
• (The horizontal coordinate is less than zero.)

Advanced Usage

• "absciss of a point": the specific x-coordinate value for a given point.

  • To find the absciss of the intersection, solve for x in the equations. (Determine the x-coordinate of where two lines cross.)

• "absciss axis": another term for the x-axis, the horizontal line in a graph.

  • The absciss axis runs left to right on the coordinate plane. (The horizontal reference line.)

Variants and Related Words

• Abscissa (n): the more common form of the word, meaning the same thing.

  • The abscissa is the first number in an ordered pair. (The x-coordinate.)

• Abscissae (n, plural): multiple abscissas.

  • The abscissae of several points were recorded in the table. (The x-coordinates.)

Synonyms

• X-coordinate: the horizontal value in a coordinate pair.
• Horizontal coordinate: the position along the x-axis.
