# What does ordinate and abscissa means

Kalabar**Bralrajas**

An ordered pair consists of two terms—the abscissa (horizontal, usually x) and the ordinate (vertical, usually y)—which define the location of a point in. Illustrated definition of Abscissa: The horizontal (x) value in a pair of coordinates. (The second value "5" shows how far up or down and is called the Ordinate). ab·scis·sa \ab-ˈsi-sə\ noun *: the horizontal coordinate of a point in a plane Cartesian coordinate system obtainedby measuring parallel to the x-axis.

Abscissa definition, (in plane Cartesian coordinates) the x-coordinate of a point: its distance from the y-axis measured parallel to the x-axis. See more. Abscissa & Ordinate. Let's plot few points on this Cartesian plane. Point P is 2 cm from Y axis & 3 cm from X axis. For this we draw perpendiculars PM on the x. The abscissa is the x-coordinate of a point on the coordinate plane. The distance along the horizontal axis. Pronounced "ab-siss-ah" (the 'c' is silent).

The curve x = a is the vertical line that goes through (a, 0) in the plane. If you write it as { (a, y) ∣ y ∈ R }, you can see that the parameter that fluctuates is the. For 3D diagrams, the names "abscissa" and "ordinate" are rarely used for x and y, respectively. When they are, the z-coordinate is sometimes.
