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

**Changing Standard Form To Slope Intercept Form** – Among the many forms used 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 solve a line equation as long as that you have the slope of the straight line and the y-intercept. This is the y-coordinate of the point at the y-axis is intersected by the line. Read more about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three primary forms of linear equations: standard slope-intercept, the point-slope, and the standard. Although they may not yield similar results when used, you can extract the information line that is produced quicker with this slope-intercept form. Like the name implies, this form utilizes an inclined line where you can determine the “steepness” of the line is a reflection of its worth.

This formula can be utilized to find the slope of a straight line, the y-intercept, also known as x-intercept which can be calculated using a variety of formulas available. The equation for a line using this formula is **y = mx + b**. The slope of the straight line is represented in the form of “m”, while its y-intercept is signified through “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” have to remain 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 used frequently to depict how an object or issue evolves over its course. The value provided by the vertical axis indicates how the equation addresses the intensity of changes over what is represented through the horizontal axis (typically times).

One simple way to illustrate the use of this formula is to find out the rate at which population increases in a specific area as the years go by. Based on the assumption that the area’s population increases yearly by a specific fixed amount, the values of the horizontal axis will rise by a single point as each year passes, and the value of the vertical axis will increase to show the rising population by the fixed amount.

Also, you can note the starting value of a question. The starting value occurs at the y value in the yintercept. The Y-intercept is the place at which x equals zero. In the case of the problem mentioned above the beginning point could be the time when the reading of population starts or when the time tracking starts along with the changes that follow.

Thus, the y-intercept represents the point that the population begins to be tracked for research. Let’s assume that the researcher starts to calculate or take measurements in the year 1995. Then the year 1995 will be considered to be the “base” year, and the x=0 points would occur in the year 1995. Therefore, you can say that the population in 1995 will be the “y-intercept.

Linear equation problems that use straight-line equations are typically solved in this manner. The starting point is depicted by the y-intercept and the change rate is represented as the slope. The primary complication of an interceptor slope form usually lies in the horizontal variable interpretation especially if the variable is accorded to a specific year (or any kind of unit). The most important thing to do is to ensure that you are aware of the variables’ meanings in detail.
