What is the straight vertical line in math?

The most common way to represent the absolute value of a number or expression is to surround it with the absolute value symbol: two vertical straight lines. |6| = 6 means “the absolute value of 6 is 6.” |–6| = 6 means “the absolute value of –6 is 6.”

What is a vertical line on a graph called?

The vertical line in the given graph is called Y-axis. In the Cartesian coordinate system, the vertical reference line is called Y-axis.

What is a horizontal line in math?

A horizontal line is a straight line that goes from left to right or right to left. In coordinate geometry, a line is said to be horizontal if two points on the line have the same Y- coordinate points. It comes from the term “horizon”. It means that the horizontal lines are always parallel to the horizon or the x-axis.

What does a vertical bar mean in math?

The vertical bar is often called a ‘pipe’. It is often used in mathematics, logic and statistics. It typically is read as ‘given that’. In probability and statistics it often indicates conditional probability, but can also indicate a conditional distribution. You can read it as ‘conditional on’.

What is the vertical bar called?

pipe
Alternatively referred to as a vertical bar, the pipe is a computer keyboard key “|” is a vertical line, sometimes depicted with a gap. This symbol is found on the same United States QWERTY keyboard key as the backslash key. Where is the pipe on the keyboard?

What slope is a vertical line?

undefined slope
Vertical lines have an undefined slope because the horizontal change is 0 — you cannot divide a number by 0.

What does vertical line mean?

Definition of vertical line : a line perpendicular to a surface or to another line considered as a base: such as. a : a line perpendicular to the horizon. b : a line parallel to the sides of a page or sheet as distinguished from a horizontal line.

What is the horizontal and vertical line?

Horizontal lines go side to side and have a slope of 0. Vertical lines go up and down and have a slope that is undefined. Graphs of horizontal lines are parallel to the x-axis. Graphs of vertical lines are parallel to the y-axis.
