## What is the XY axis?

An x-y axis, also known as a cartesian coordinate system or a coordinate plane, is a two-dimensional plane of points defined uniquely by a pair of coordinates. The horizontal line, then, is known as the x axis and measures the distance left or right from the vertical line.

## What is the XY plane?

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. The first octant, in the foreground, is determined by the positive axes.

**Why is 0 0 called the origin?**

In two dimensions On the flat coordinate plane, there are two axes, the vertical y-axis and the horizontal x-axis. The origin is the point where they intersect. This point has the coordinates 0,0 and is usually labelled with the letter O.

**Why are co ordinates of a point referred to as Cartesian coordinates?**

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 are the X and y axis used for?

The Y axis refers to vertical position (perpendicular to the base) and the X axis refers to the horizontal position (parallel to the base). As seen in Figure 6a below. When aligning vertical rotating machinery, the Z axis is also the center of rotation, however X and Y are used to reference the two axial planes 90 degrees from each other as in

### Which axis is read first X or Y?

The x-axis is the horizontal axis and the y-axis is the vertical (straight up and down) axis. When denoting a point in the x-y plane, you always denote the x-value first and the y-value second. That is any arbitrary x-value and y-value are denoted as (x,y).

**Which comes first x axis or the Y axis?**

To plot a single point on the axis, we start with a coordinate, which is a pair of points each representing a distance travelled on an axis. The x-axis comes first, and then the y-axis. For the point (1,2), the x- coordinate is 1 and the y- coordinate is 2. Here’s how we’d plot that on a graph:

**What is the origin of the X and y axis?**

X and y axis. The x-axis and y-axis are axes in the Cartesian coordinate system. Together, they form a coordinate plane. The x-axis is usually the horizontal axis, while the y-axis is the vertical axis. They are represented by two number lines that intersect perpendicularly at the origin, located at (0, 0), as shown in the figure below.
