## The Definition, Formula, and Problem Example of the Slope-Intercept Form

**How To Get Slope Intercept Form** – One of the many forms that are used to represent a linear equation, the one most frequently seen is the **slope intercept form**. The formula of the slope-intercept identify a line equation when you have the slope of the straight line and the y-intercept. It is the y-coordinate of the point at the y-axis crosses the line. Find out more information about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three main forms of linear equations: the traditional one, the slope-intercept one, and the point-slope. While they all provide identical results when utilized, you can extract the information line generated more efficiently with this slope-intercept form. Like the name implies, this form employs the sloped line and you can determine the “steepness” of the line reflects its value.

The formula can be used to discover the slope of a straight line. It is also known as y-intercept, or x-intercept, in which case you can use a variety of formulas available. The equation for this line in this specific formula is **y = mx + b**. The slope of the straight line is indicated through “m”, while its intersection with the y is symbolized by “b”. Every point on the straight line can be represented using an (x, y). Note that in the y = mx + b equation formula, the “x” and the “y” must remain as variables.

## An Example of Applied Slope Intercept Form in Problems

The real-world in the real world, the slope intercept form is used frequently to depict how an object or problem changes in the course of time. The value of the vertical axis represents how the equation tackles the degree of change over what is represented by the horizontal axis (typically in the form of time).

A simple example of the use of this formula is to find out the rate at which population increases in a certain area as time passes. If the area’s population grows annually by a certain amount, the value of the horizontal axis will grow one point at a time for every passing year, and the amount of vertically oriented axis will increase to show the rising population by the amount fixed.

It is also possible to note the beginning value of a question. The starting value occurs at the y value in the yintercept. The Y-intercept is the point where x is zero. If we take the example of the problem mentioned above the beginning value will be at the time the population reading starts or when the time tracking starts, as well as the related changes.

Thus, the y-intercept represents the place that the population begins to be documented for research. Let’s say that the researcher starts to perform the calculation or take measurements in 1995. This year will represent considered to be the “base” year, and the x = 0 points will be observed in 1995. So, it is possible to say that the population in 1995 represents the “y”-intercept.

Linear equation problems that utilize straight-line equations are typically solved this way. The starting point is represented by the y-intercept, and the change rate is expressed as the slope. The main issue with the slope intercept form usually lies in the horizontal variable interpretation in particular when the variable is attributed to an exact year (or any kind or unit). The most important thing to do is to ensure that you are aware of the meaning of the variables.
