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

**X=-3 In Slope Intercept Form** – One of the numerous forms used to illustrate a linear equation the one most commonly used is the **slope intercept form**. It is possible to use the formula for the slope-intercept to identify a line equation when that you have the slope of the straight line and the y-intercept, which is the y-coordinate of the point at the y-axis intersects the line. Learn more about this specific line equation form below.

## What Is The Slope Intercept Form?

There are three main forms of linear equations: the standard, slope-intercept, and point-slope. While they all provide similar results when used, you can extract the information line faster using this slope-intercept form. It is a form that, as the name suggests, this form utilizes a sloped line in which the “steepness” of the line determines its significance.

This formula is able to find the slope of a straight line, the y-intercept or x-intercept in which case you can use a variety of formulas available. The line equation of this specific formula is **y = mx + b**. The slope of the straight line is represented with “m”, while its y-intercept is signified with “b”. Every point on the straight line can be represented using 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 often utilized to depict how an object or issue changes over an elapsed time. The value that is provided by the vertical axis represents how the equation addresses the extent of changes over what is represented via the horizontal axis (typically time).

A simple example of the application of this formula is to determine how the population grows within a specific region as the years go by. Using the assumption that the area’s population increases yearly by a predetermined amount, the point value of the horizontal axis will increase by one point each year and the point values of the vertical axis will grow to represent the growing population by the fixed amount.

It is also possible to note the starting value of a problem. The starting point is the y-value in the y-intercept. The Y-intercept marks the point at which x equals zero. By using the example of the above problem the beginning value will be at the time the population reading starts or when the time tracking begins along with the related changes.

The y-intercept, then, is the point where the population starts to be recorded by the researcher. Let’s say that the researcher begins to perform the calculation or measurement in 1995. In this case, 1995 will be”the “base” year, and the x 0 points will occur in 1995. This means that the 1995 population corresponds to the y-intercept.

Linear equation problems that utilize straight-line formulas are nearly always solved in this manner. The starting point is represented by the yintercept and the rate of change is represented through the slope. The primary complication of the slope intercept form usually lies in the horizontal interpretation of the variable especially if the variable is linked to one particular year (or any other kind of unit). The most important thing to do is to ensure that you are aware of the variables’ definitions clearly.
