 # Question: What Is An Ordinate In Math?

## What is abscissa and ordinate in math?

In mathematics, the abscissa (/æbˈsɪs.

ə/; plural abscissae or abscissæ or abscissas) and the ordinate are respectively the first and second coordinate of a point in a coordinate system: abscissa -axis (horizontal) coordinate ordinate -axis (vertical) coordinate..

## What is an abscissa in math?

: the horizontal coordinate of a point in a plane Cartesian coordinate system obtained by measuring parallel to the x-axis — compare ordinate.

## How do you calculate abscissa?

The horizontal (“x”) value in a pair of coordinates. How far along the point is. Always written first in an ordered pair of coordinates such as (12,5). In this example, the value “12” is the abscissa.

## What is ordinate point?

The ordinate is the y-coordinate of a point on the coordinate plane. The distance along the vertical (y) axis. The x-coordinate of a point is called the “abscissa”. For more see Coordinates of a point.

## What is a theorem?

1 : a formula, proposition, or statement in mathematics or logic deduced or to be deduced from other formulas or propositions. 2 : an idea accepted or proposed as a demonstrable truth often as a part of a general theory : proposition the theorem that the best defense is offense.

## What do you call the first coordinate?

A relation is a set of ordered pairs. The first coordinate (usually the x-coordinate) is called the domain and the second (usually the y-coordinate) is called the range.

## Which is called abscissa?

The abscissa is also known as the “x” coordinate of a point, shown on the horizontal line, with the ordinate, also known as the “y” coordinate, shown on the vertical line. … The point has 3 as its abscissa and 2 as its ordinate.

## What is Y coordinate called?

A y-coordinate is the second element in an ordered pair. When an ordered pair is graphed as the coordinates of a point in the coordinate plane, the y-coordinate represents the directed distance of the point from the x-axis. Another name for the y-coordinate is the ordinate.

## How do you use abscissa?

Abscissa sentence examplesThe ordinate of the trapezette will be denoted by u, and the abscissa of this ordinate, i.e. … The measured lengths are marked off on ordinates erected on an abscissa, along which the times are noted. … the ordinate whose abscissa is xo+ z H.More items…

## What is abscissa and ordinate Class 9?

For example, if (x, y) is an ordered pair, then y is the ordinate here. An ordered pair is used to denote a point in the Cartesian plane. It is the second of the two terms (x, y) by which a point is defined, in a system of fixed Cartesian Coordinate plane. The first coordinate (x), in the plane, is called the abscissa.

## What do you mean by ordinate?

The definition of an ordinate is a value of a coordinate on the vertical axis. … The distance of a point from the x-axis on a graph in the Cartesian coordinate system. It is measured parallel to the y-axis. For example, a point having coordinates (2,3) has 3 as its ordinate.

## What is the abscissa of 3?

Answer. Abscissa of (3,-5) = 3 that is x cordinate.

## How do you find ordinates?

The vertical (“y”) value in a pair of coordinates. How far up or down the point is. Always written second in an ordered pair of coordinates such as (12,5). In this example, the value “5” is the ordinate.

## What is the abscissa of point (- 3 4?

ABSCISSA OF THE POINT (-3. 4) IS (-3). AS THE ABSCISSA IS THE VALUE OF X-AXIS AND IN THIS POINT X-AXIS IS -3.
