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

**Slope Intercept Form Vs Point Slope** – One of the numerous forms employed to represent a linear equation, one that is frequently seen is the **slope intercept form**. You can use the formula of the slope-intercept to identify a line equation when that you have the straight line’s slope , and the y-intercept, which is the y-coordinate of the point at the y-axis crosses the line. Read more about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three main forms of linear equations: standard slope, slope-intercept and point-slope. While they all provide the same results when utilized but you are able to extract the information line generated more efficiently by using this slope-intercept form. As the name implies, this form makes use of a sloped line in which the “steepness” of the line indicates its value.

This formula can be used to calculate a straight line’s slope, the y-intercept or x-intercept which can be calculated using a variety of available formulas. The line equation in this particular formula is **y = mx + b**. The straight line’s slope is indicated in the form of “m”, while its intersection with the y is symbolized through “b”. Each point of the straight line is represented as an (x, y). Note that in the y = mx + b equation formula, the “x” and the “y” need to remain variables.

## An Example of Applied Slope Intercept Form in Problems

When it comes to the actual world in the real world, the slope-intercept form is frequently used to illustrate how an item or issue changes over the course of time. The value provided by the vertical axis is a representation of how the equation handles the degree of change over the value provided through the horizontal axis (typically the time).

An easy example of the application of this formula is to find out the rate at which population increases in a certain area as time passes. Based on the assumption that the area’s population grows annually by a specific fixed amount, the point value of the horizontal axis increases by one point with each passing year and the values of the vertical axis will increase to reflect the increasing population by the set amount.

It is also possible to note the starting point of a question. The beginning value is located at the y value in the yintercept. The Y-intercept represents the point at which x equals zero. By using the example of a previous problem the starting point would be at the point when the population reading begins or when the time tracking begins along with the associated changes.

Thus, the y-intercept represents the location that the population begins to be tracked by the researcher. Let’s say that the researcher began to do the calculation or measure in the year 1995. In this case, 1995 will serve as”the “base” year, and the x = 0 point would occur in the year 1995. Thus, you could say that the population of 1995 is the y-intercept.

Linear equations that use straight-line formulas are almost always solved in this manner. The initial value is represented by the yintercept and the rate of change is expressed by the slope. The primary complication of the slope-intercept form generally lies in the horizontal interpretation of the variable in particular when the variable is linked to an exact year (or any type in any kind of measurement). The most important thing to do is to make sure you understand the variables’ meanings in detail.
