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

**Equation To Slope Intercept Form** – One of the numerous forms used to depict a linear equation, among the ones most commonly found is the **slope intercept form**. It is possible to use the formula for the slope-intercept in order to identify a line equation when you have the straight line’s slope , and the y-intercept, which is the y-coordinate of the point at 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 one, the slope-intercept one, and the point-slope. Though they provide the same results when utilized, you can extract the information line that is produced quicker through an equation that uses the slope-intercept form. It is a form that, as the name suggests, this form uses an inclined line, in which it is the “steepness” of the line reflects its value.

This formula is able to calculate the slope of a straight line. It is also known as the y-intercept or x-intercept where you can utilize a variety formulas that are available. The line equation in this formula is **y = mx + b**. The slope of the straight line is symbolized by “m”, while its intersection with the y is symbolized via “b”. Each point of 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

When it comes to the actual world, the slope intercept form is used frequently to show how an item or problem changes in its course. The value provided by the vertical axis is a representation of how the equation handles the intensity of changes over what is represented through the horizontal axis (typically times).

A simple example of using this formula is to find out how much population growth occurs within a specific region in the course of time. Based on the assumption that the population of the area increases each year by a specific fixed amount, the values of the horizontal axis will grow one point at a moment as each year passes, and the point amount of vertically oriented axis will rise to reflect the increasing population by the fixed amount.

Also, you can note the beginning value of a challenge. The beginning value is at the y value in the yintercept. The Y-intercept is the point where x is zero. By using the example of a previous problem the beginning point could be at the time the population reading begins or when the time tracking begins , along with the related changes.

This is the place that the population begins to be recorded to the researchers. Let’s assume that the researcher is beginning with the calculation or measurement in the year 1995. The year 1995 would represent”the “base” year, and the x = 0 point will be observed in 1995. Therefore, you can say that the population in 1995 will be the “y-intercept.

Linear equations that use straight-line formulas are nearly always solved in this manner. The beginning value is depicted by the y-intercept and the change rate is expressed through the slope. The most significant issue with the slope intercept form usually lies in the interpretation of horizontal variables, particularly if the variable is linked to the specific year (or any kind of unit). The trick to overcoming them is to make sure you comprehend the variables’ meanings in detail.
