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

**Graphing Using Slope Intercept Form** – There are many forms employed to illustrate a linear equation among the ones most commonly encountered is the **slope intercept form**. You can use the formula of the slope-intercept to identify a line equation when you have the straight line’s slope , and the y-intercept. It is the coordinate of the point’s y-axis where the y-axis is intersected by the line. Find out more information about this particular line equation form below.

## What Is The Slope Intercept Form?

There are three basic forms of linear equations: the standard, slope-intercept, and point-slope. Even though they can provide similar results when used however, you can get the information line that is produced quicker by using the slope-intercept form. Like the name implies, this form utilizes the sloped line and you can determine the “steepness” of the line determines its significance.

This formula can be used to calculate the slope of straight lines, the y-intercept, also known as x-intercept which can be calculated using a variety of formulas available. The line equation in this particular formula is **y = mx + b**. The straight line’s slope is represented with “m”, while its y-intercept is signified with “b”. Each point of the straight line is represented by an (x, y). Note that in the y = mx + b equation formula the “x” and the “y” are treated as 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 often utilized to show how an item or issue changes over the course of time. The value provided by the vertical axis represents how the equation tackles the extent of changes over the value given via the horizontal axis (typically in the form of time).

A simple example of using this formula is to find out how many people live in a particular area as time passes. If the population of the area increases each year by a certain amount, the values of the horizontal axis increases by one point for every passing year, and the amount of vertically oriented axis is increased to reflect the increasing population according to the fixed amount.

Also, you can note the starting point of a challenge. The beginning value is at the y’s value within the y’intercept. The Y-intercept marks the point where x is zero. By using the example of the above problem the starting point would be at the time the population reading begins or when the time tracking starts, as well as the associated changes.

The y-intercept, then, is the location where the population starts to be recorded in the research. Let’s say that the researcher began to perform the calculation or the measurement in the year 1995. The year 1995 would become”the “base” year, and the x = 0 points will occur in 1995. So, it is possible to say that the population of 1995 represents the “y”-intercept.

Linear equations that employ straight-line formulas are nearly always solved this way. The beginning value is expressed by the y-intercept and the rate of change is expressed in the form of the slope. The primary complication of an interceptor slope form typically lies in the horizontal variable interpretation particularly when the variable is linked to one particular year (or any other kind number of units). The trick to overcoming them is to make sure you understand the variables’ definitions clearly.
