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

**How To Change Slope Intercept To Standard Form** – One of the numerous forms used to depict a linear equation, one that is commonly encountered is the **slope intercept form**. You can use the formula for the slope-intercept in order to solve a line equation as long as that you have the slope of the straight line and the y-intercept. This is the coordinate of the point’s y-axis where the y-axis intersects the line. Learn more about this particular line equation form below.

## What Is The Slope Intercept Form?

There are three fundamental forms of linear equations: the standard slope, slope-intercept and point-slope. While they all provide identical results when utilized but you are able to extract the information line produced faster with an equation that uses the slope-intercept form. Like the name implies, this form uses a sloped line in which the “steepness” of the line is a reflection of its worth.

This formula can be used to discover a straight line’s slope, the y-intercept (also known as the x-intercept), where you can apply different formulas that are available. The line equation in this specific formula is **y = mx + b**. The slope of the straight line is signified by “m”, while its y-intercept is represented through “b”. Each point of the straight line is represented with 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

For the everyday world in the real world, the slope-intercept form is frequently used to show how an item or issue evolves over an elapsed time. The value that is provided by the vertical axis is a representation of how the equation deals with the magnitude of changes in what is represented via the horizontal axis (typically the time).

One simple way to illustrate the application of this formula is to discover how the population grows in a specific area as the years go by. If the area’s population grows annually by a certain amount, the worth of horizontal scale will grow one point at a time as each year passes, and the value of the vertical axis is increased to represent the growing population by the fixed amount.

It is also possible to note the starting point of a question. The starting value occurs at the y-value in the y-intercept. The Y-intercept represents the point at which x equals zero. Based on the example of a problem above the beginning point could be at the time the population reading starts or when the time tracking starts along with the changes that follow.

The y-intercept, then, is the location where the population starts to be monitored to the researchers. Let’s suppose that the researcher begins to perform the calculation or take measurements in the year 1995. The year 1995 would represent the “base” year, and the x 0 points would occur in the year 1995. This means that the population of 1995 is the y-intercept.

Linear equations that employ straight-line formulas can be solved this way. The starting value is represented by the yintercept and the rate of change is represented through the slope. The primary complication of this form is usually in the horizontal variable interpretation in particular when the variable is linked to a specific year (or any type in any kind of measurement). The most important thing to do is to ensure that you are aware of the variables’ definitions clearly.
