# Quick Answer: What Is Cartesian Plane In Math?

## What is a Cartesian plane used for?

Measurement and Geometry The number plane or Cartesian plane is like two number lines that cross at zero; one of them is horizontal and the other is vertical. The Cartesian coordinate system is used to plot points.

## What is a Cartesian plane called?

The two-dimensional plane is called the Cartesian plane, or the coordinate plane and the axes are called the coordinate axes or x-axis and y-axis. The given plane has four equal divisions by origin called quadrants.

## What is Cartesian plane class 9?

In Mathematics, the cartesian plane is defined as a two-dimensional coordinate plane, which is formed by the intersection of the x-axis and y-axis. The x-axis and y-axis intersect perpendicular to each other at the point called the origin.

## How do you work out a Cartesian plane?

The position of any point on the Cartesian plane is described by using two numbers: (x, y). The first number, x, is the horizontal position of the point from the origin. It is called the x-coordinate. The second number, y, is the vertical position of the point from the origin.

## Why is it called the Cartesian plane?

The Cartesian coordinate system is used to plot points. The Cartesian plane is named after the French mathematician and philosopher René Descartes (1596–1650), who introduced the coordinate system to show how algebra could be used to solve geometric problems.

## Why is it called Cartesian?

They are called Cartesian because the idea was developed by the mathematician and philosopher Rene Descartes who was also known as Cartesius. He is also famous for saying “I think, therefore I am”.

## What does Cartesian mean?

Cartesian (Adjective) Of, or pertaining to, Descartes, his mathematical methods, or his philosophy, especially with regard to its emphasis on logical analysis and its mechanistic interpretation of physical nature.

## Is Y or Z vertical?

X-axis and Y-axis make up the horizontal plane. Positive Y-axis is north and positive X-axis is east. Z-axis is always the vertical axis and is positive upwards.

## What does ordinate mean?

The definition of an ordinate is a value of a coordinate on the vertical axis. A coordinate on a plane that is vertical and measured in relation to the x axis is an example of an ordinate.

## In which quadrant does the point 3 lie?

Explanation- As – 3 will lie in x axis and – 3 will lie in y-axis so it will be the third quadrant.

## What is the definition of abscissa?

In common usage, the abscissa refers to the horizontal (x) axis and the ordinate refers to the vertical (y) axis of a standard two-dimensional graph. In mathematics, the abscissa (/æbˈsɪs.

## What does Cartesian coordinates mean?

The Cartesian coordinates (also called rectangular coordinates ) of a point are a pair of numbers (in two-dimensions) or a triplet of numbers (in three-dimensions) that specified signed distances from the coordinate axis.

## How many quadrants are in the Cartesian plane?

The number plane, or Cartesian plane, is divided into four quadrants by two perpendicular lines called the x-axis, a horizontal line, and the y-axis, a vertical line. These axes intersect at a point called the origin.
