# What are the 4 coordinate planes?

## What are the 4 coordinate planes?

Here are the characteristics for each of the four coordinate plane quadrants:

• Quadrant I: positive x and positive y.
• Quadrant II: negative x and positive y.
• Quadrant III: negative x and negative y.
• Quadrant IV: positive x and negative y.

## How many coordinate planes are there?

three coordinate planes
The three coordinate axes determine the three coordinate planes illustrated in Figure 3(a). The xy-plane is the plane that contains the x- and y-axes; the yz-plane contains the y- and z-axes; the xz-plane contains the x- and z-axes. These three coordinate planes divide space into eight parts, called octants.

What is an example of a coordinate plane?

For people to use coordinate planes, they need to have a common language. By convention, we normally call the horizontal number line the x-axis, and we normally call the vertical number line the y-axis. For example, this point would be named (6, 2) since 6 is its x-coordinate and 2 is its y-coordinate.

### What are the coordinate plane quadrants?

The coordinate plane is divided into four quadrants. Quadrant one (QI) is the top right fourth of the coordinate plane, where there are only positive coordinates. Quadrant two (QII) is the top left fourth of the coordinate plane. Quadrant three (QIII) is the bottom left fourth.

### Why is it called Cartesian plane?

A Cartesian plane (named after French mathematician Rene Descartes, who formalized its use in mathematics) is defined by two perpendicular number lines: the x-axis, which is horizontal, and the y-axis, which is vertical. Using these axes, we can describe any point in the plane using an ordered pair of numbers.

What is coordinates in Cartesian plane?

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.

#### What is Cartesian formula?

Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)2 + (y − b)2 = r2 where a and b are the coordinates of the center (a, b) and r is the radius.

#### Is Y or Z vertical?

These axes are normally taken so that X axis is the longitudinal axis pointing ahead, Z axis is the vertical axis pointing downwards, and the Y axis is the lateral one, pointing in such a way that the frame is right-handed.

What is the center of a coordinate plane called?

The center of the coordinate system (where the lines intersect) is called the origin. The axes intersect when both x and y are zero. The coordinates of the origin are (0, 0). To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

## What are the 4 quadrants?

The x and the y axes divide the plane into four graph quadrants. These are formed by the intersection of the x and y axes and are named as: Quadrant I, II, III, and IV. In words, we call them first, second, third, and fourth quadrant.

## Why is it called a coordinate plane?

The invention of the Cartesian Coordinate System is credited to René Descartes. He revolutionised mathematics by providing the first systematic link between Euclidean geometry and algebra. Thus, the Coordinate Plane is named after him.

What is the middle of a Cartesian plane called?

As you remember from pre-algebra a coordinate plane is a two-dimensional number line where the vertical line is called the y-axis and the horizontal is called the x-axis. These lines are perpendicular and intersect at their zero points. This point is called the origin.

### Is the coordinate plane dimensioned in customary units?

The coordinate planes are dimensioned in customary or metric units, just like the blank graph paper on the site. There are versions of the coordinate plane with and without axis labels, as well as versions that show the quadrant numbers in light text in the background of each quadrant.

### Which is the origin of the coordinate plane?

The coordinate plane is a system for graphing and describing points and lines. The coordinate plane is comprised of a horizontal (x -) axis and a vertical (y-) axis. The intersection of these lines creates the origin, which is the point (0,0) (0, 0). The coordinate plane is split into four quadrants.

Which is Quadrant 1 of the coordinate plane?

Quadrant 1 of the coordinate plane deals with positive x axis and y axis values, and it is often the first place students start graphing linear functions.

#### When did Descartes invent the coordinate system?

The coordinate plane was developed centuries ago (in 1637, to be exact) and refined by the French mathematician René Descartes. In his honor, the system is sometimes called the Cartesian coordinate system. The coordinate plane can be used to plot points and graph lines.
