noun. The y-axis is the vertical axis in a graph. An example of an y-axis is the axis that runs up and down on a graph.

## Similarly, you may ask, what direction is the Y axis?

The y-axis is like a vertical ruler. It shows you where an object on a Cartesian plane, a two-dimensional mathematical graph, is in the y (vertical) direction. It is also the starting, or zero, point for measuring how far a point is to the right or left (horizontally) on a graph.

## Accordingly, what are Y axis?

A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin. The x-coordinate is 2.

## What is the positive y direction?

The horizontal line to the right of the origin is called the positive X axis and the horizontal line to the left of the origin is called the negative X axis. The vertical line above the origin is called the positive Y axis and the vertical line below the origin is called the negative X axis.

## What is another name for the y coordinate?

The ordinate is another name for the y (vertical) coordinate of a point. Pronounced “ORD-inet”. Most commonly, the term “y-coordinate” is used.

## What is positive direction?

Positive Direction. The direction which lines of force are assumed to take in the air or outer circuit from a positive to a negative region. It applies to electrostatic, to magnetic and to electro-magnetic lines of force.

## What does Y mean in math?

The symbol stands for an unknown number, the symbol y stands for an unknown number and the symbol 2 stands for a known number, two. In algebra when two symbols that stand for a number are placed beside each other the operation between them is taken to be multiplication.

## What does the Y axis represent on a graph?

x-axis (in mathematics) The horizontal line at the bottom of a graph, which can be labeled to give information about what the graph represents. y-axis (in mathematics) The vertical line to the left or right of a graph, which can be labeled to give information about what the graph represents.

## What is the equation for y axis?

The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it. Let P (x, y) be any point on the y-axis. Then clearly, for all position of P we shall the same abscissa 0 or, x = 0. Therefore, the equation of y-axis is x = 0.

## Which is the Y axis on a bar graph?

Bar graphs have a labeled x-axis (horizontal axis) and y-axis (vertical axis). When experimental data is graphed, the independent variable is graphed on the x-axis, while the dependent variable is graphed on the y-axis.

## What is the Y value called?

The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value “5” is the Y Coordinate. Also called “Ordinate”

## Is the Y axis the dependent variable?

Scientists like to say that the “independent” variable goes on the x-axis (the bottom, horizontal one) and the “dependent” variable goes on the y-axis (the left side, vertical one).

## What does Y axis mean in math?

(in a plane Cartesian coordinate system) the axis, usually vertical, along which the ordinate is measured and from which the abscissa is measured. (in a three-dimensional Cartesian coordinate system) the axis along which values of y are measured and at which both x and z equal zero.

## What does Y intercept mean?

Definition of y-intercept. : the y-coordinate of a point where a line, curve, or surface intersects the y-axis.

## How do you label a graph?

To properly label a graph, you should identify which variable the x-axis and y-axis each represent. Don’t forget to include units of measure (called scale) so readers can understand each quantity represented by those axes. Finally, add a title to the graph, usually in the form “y-axis variable vs. x-axis variable.”

## What is the Y direction?

Noun. y-direction. (algebraic geometry) The direction aligned with the y-axis of a coordinate system.

## Similarly, what is Y coordinate?

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 find the Y coordinate?

To find out the coordinates of a point in the coordinate system you do the opposite. Begin at the point and follow a vertical line either up or down to the x-axis. There is your x-coordinate. And then do the same but following a horizontal line to find the y-coordinate.
