The horizontal line can be interpreted as straight lines that rest in the direction of left to right. The horizontal lines consist of the identical coordinates of Y-Coordinate. The horizontal lines are known to be always parallel to the X-Coordinate.

## Slope of the Horizontal Line

The slope of the horizontal line is understood to be 0. The slope of the horizontal lines is illustrated by m. And m in the case of the horizontal lines is 0.

## Horizontal Line Test

The prime function of the horizontal line test is to specify if the provided function is a one-to-one function. The horizontal line test depicts that a given function is not a one-to-one function if there rests any horizontal line.

## Steps to Draw the Horizontal Lines

Knowing the ways of the procedure to bring out the horizontal lines is very crucial in understanding the concepts of horizontal lines. The steps to draw the horizontal lines are:

- In the prime stage to draw any horizontal line given, one should recognize the magnitudes of the X-value and the Y-value.
- Then, in the successive stage, one has to get to the points in the plane of XY.
- Then, in the next stage, a parallel line will be drawn that will be parallel to the X-axis.
- Consequently, a horizontal line will be drawn.

## Examples of the Horizontal Lines

Examples of horizontal lines are:

- Presuming that Y is 10.
- Presuming that Y is -5.
- Presuming that Y is 18.
- Presuming that Y is -19.
- Presuming that Y is 88.

## Real-Life Examples of the Horizontal Lines

A few of the actual life examples of horizontal lines are:

- Suppose there is a ladder that is laying on the ground in the position or the direction from left to right, then that ladder will be considered to be the horizontal line.
- Suppose that there is a person who is doing any yoga position, in which that person has to rest in the direction from the left to right. Then, that person is considered to be laying in the horizontal line.
- Presume that there is a small stick that is resting on the floor in the direction from the left to the right. Then, that stick is considered to be laying in the horizontal line.
- Suppose that there is a pencil that is resting on the table in the direction of the left to the right. Then, that pencil is considered to be laying in the horizontal line.

## Vertical Lines

The vertical line can be interpreted as the lines that are straight and that straight line is parallel to the Y-axis. The vertical lines rest in the direction from the top to the underneath. vertical lines are considered to have not any slopes.

## Slope of the Vertical Line

The slope of the vertical line is understood to be undefined.

## Examples of Vertical Lines

A few examples of vertical lines are:

- Presuming that X is 100.
- Presuming that X is 99.
- Presuming that X is 34.
- Presuming that X is 65.
- Presuming that X is 29.

## Real-Life Examples of the Vertical Lines

A few of the actual life examples of the vertical lines are illustrated below;

- Suppose that there is fencing done in the direction from the top to the bottom. Then, that fencing is known to be in the vertical line.
- When there are poles in the direction from the top to the bottom, then those poles are known to be in the vertical line.
