## Which is first X or Y?

## Which is first X or Y?

x-coordinate

In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate. Note that the x-coordinate is listed before the y-coordinate. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0). Consider the point below.

**What is an X and y-axis chart called?**

The x-axis is also known as abscissa or x graph whereas the y-axis is also known as ordinate or y graph.

### What is an X and Y chart?

A x and y graph can be defined by the two axes i.e. x-axis and the y-axis that form a coordinate plane for a graph. The horizontal axis is represented by the x-axis and the vertical axis is represented by the y-axis.

**Does y go up or down?**

Reminder: the x-axis really runs left and right, and the y-axis runs up and down.

#### What is y-axis also called?

Also called axis of ordinates. (in a plane Cartesian coordinate system) the axis, usually vertical, along which the ordinate is measured and from which the abscissa is measured.

**What directions are XY and Z?**

The x axis is in the plane of the screen and is positive toward the right and negative toward the left. The y axis is in the plane of the screen and is positive toward the top and negative toward the bottom. The z axis is perpendicular to the screen or keyboard, and is positive extending outward from the screen.

## Is XY male or female?

The twenty third pair is called the sex chromosomes, while the rest of the 22 pairs are called autosomes. Typically, biologically male individuals have one X and one Y chromosome (XY) while those who are biologically female have two X chromosomes.

**Is XY a girl or boy?**

Each sperm carries either an X chromosome or no sex chromosome at all – but once again, as in XY, the father’s contribution determines the sex of the offspring. Figure 1: Five (of many) sex determination systems. A. XY system In humans, females are XX and males are XY.

### What is the z coordinate called?

the applicate

For 3D diagrams, the names “abscissa” and “ordinate” are rarely used for x and y, respectively. When they are, the z-coordinate is sometimes called the applicate. The words abscissa, ordinate and applicate are sometimes used to refer to coordinate axes rather than the coordinate values.

**Where does Z go up or down?**

The Z axis is perpendicular to the ground plane; think of it as a line drawn between the device and the center of the Earth. The value of the Z coordinate is positive upward (away from the center of the Earth) and negative downward (toward the center of the Earth).
