# Straight Lines – A Basic Concept of Everyday Mathematics

There are a lot of topics that only students’ study in their academics, but lines are such a thing that is known to every single person. Lines are important as they are present everywhere. Mathematical geometry covers a wide range of topics. A line is one such concept that is extremely important in the world of mathematics. Horizontal lines and vertical lines are the most widely utilised lines. A one-dimensional line is made up of simple length and no width. If we want to construct a line then we require at least two pints. Lines in mathematics are defined by the angle they make with the respective plane, however, there are two major types of lines in mathematics: horizontal line and vertical lines. We’ll go over them in-depth because they’re one of the most significant topics in mathematics.

Horizontal Line: Horizon is the line where the sky meets the ocean, and the word horizontal is derived from the word horizon. When a line is drawn parallel to the x-axis, it is called a horizontal line. A horizontal line can alternatively be defined as a line with an intercept only on the y-axis and not on the x-axis. A horizontal line’s slope is always equal to zero. y = a, where an is a constant, is one of the horizontal line’s equations. Horizontal lines may be easily observed in everyday life; if one looks around their room, horizontal lines can be found everywhere; look down at the bottom of the room where the wall meets the floor, look at the roofs, and so on. All of these are instances of horizontal lines that can be found in daily life.

Lines are not only observed everywhere in our life but they also have a lot of applications. A horizontal line is used for many purposes. There is a test in mathematics known as the horizontal line test. It has great importance in determining the kind of function it is. It is an easy way of determining whether a function is one to one function or not. It is important for students to know about horizontal lines. So, that they can use them properly wherever required.

Vertical Line: Standing lines include both vertical and horizontal lines. A vertical line is always parallel to the y-axis. The vertical line is perpendicular to the x-axis at all times. A horizontal line’s slope is always ninety degrees. Only on the x-axis does the vertical line have an intercept, not on the y-axis. To depict straight lines, a variety of equations are utilised. The equation x =a, where an is a constant, represents a vertical line. Vertical lines are often seen in our everyday lives. Look at the pillars around you, the tall buildings, the legs of tables and chairs, and there are many more examples of vertical lines to be found.
