# Question: What Is Y-axis In Math?

## What is the Y-axis?

A y – axis is the vertical axis on the Cartesian coordinate plane. The y – axis starts at negative infinity and increases to positive infinity. The y – axis is also the starting, or 0 point, for measuring how far a point extends horizontally on a graph.

## What is an example of Y-axis?

An example of an y – axis is the axis that runs up and down on a graph. A similar axis that is perpendicular to the x- axis and the z- axis of a three-dimensional Cartesian coordinate system. The vertical (V), or nearest vertical, plane on a two- or three-dimensional grid, chart, or graph in a Cartesian coordinate system.

## Which line is the y-axis?

A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis.

## What is the formula for the 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.

## What’s another name for Y axis?

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. (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.

## Is Y axis up or down?

X and Y Axis The left-right (horizontal) direction is commonly called X. The up – down (vertical) direction is commonly called Y.

## What is another name for the Y-axis of a bar graph?

On a vertical bar graph, as shown above, the horizontal axis (or x – axis ) shows the data categories. In this example, they are years. The vertical axis (or y – axis ) is the scale.

## What is the y-axis in a bar graph?

In most bar graphs, like the one above, the y – axis runs vertically (us and down). Sometimes bar graphs are made so that the bars are sideways like in the graph to the left. Then the y – axis is horizontal (flat). Typically, the y – axis has numbers for the amount of stuff being measured.

## Which axis is Y 4 parallel to?

y = 4 is parallel to x – axis.

## What is the line equation of a graph?

Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis). It cuts the y-axis at -2, and this is the constant in the equation.

## What is the equation for graph?

This graph shows a straight line and the corresponding equation is y = mx + b. Y is the y value (distance along the y-axis, which is the vertical axis) and x is the x value (the distance along the x-axis, which is the horizontal axis).
