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

**Graphing Lines Using Slope Intercept Form** – There are many forms employed to illustrate a linear equation the one most commonly seen is the **slope intercept form**. It is possible to use the formula for the slope-intercept 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 meets the line. Learn more about this specific line equation form below.

## What Is The Slope Intercept Form?

There are three basic forms of linear equations: the standard slope, slope-intercept and point-slope. While they all provide similar results when used but you are able to extract the information line produced faster through the slope intercept form. It is a form that, as the name suggests, this form makes use of an inclined line, in which it is the “steepness” of the line determines its significance.

The formula can be used to find the slope of straight lines, y-intercept, or x-intercept, where you can apply different available formulas. The equation for this line in this particular formula is **y = mx + b**. The straight line’s slope is represented through “m”, while its intersection with the y is symbolized with “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” are treated as variables.

## An Example of Applied Slope Intercept Form in Problems

In the real world in the real world, the slope intercept form is commonly used to depict how an object or problem changes in an elapsed time. The value provided by the vertical axis represents how the equation deals with the magnitude of changes in the value provided by the horizontal axis (typically time).

One simple way to illustrate the use of this formula is to find out how much population growth occurs in a specific area in the course of time. Using the assumption that the area’s population increases yearly by a fixed amount, the worth of horizontal scale will grow one point at a moment each year and the point worth of the vertical scale will grow to show the rising population by the set amount.

You may also notice the beginning value of a particular problem. The starting value occurs at the y-value in the y-intercept. The Y-intercept is the point at which x equals zero. By using the example of the above problem the beginning point could be when the population reading begins or when time tracking begins , along with the changes that follow.

So, the y-intercept is the point when the population is beginning to be monitored by the researcher. Let’s assume that the researcher begins to do the calculation or the measurement in 1995. Then the year 1995 will be considered to be the “base” year, and the x = 0 point will be observed in 1995. This means that the population of 1995 corresponds to the y-intercept.

Linear equation problems that utilize straight-line formulas are almost always solved this way. The initial value is depicted by the y-intercept and the rate of change is expressed in the form of the slope. The most significant issue with this form generally lies in the interpretation of horizontal variables in particular when the variable is attributed to the specific year (or any kind in any kind of measurement). The key to solving them is to ensure that you are aware of the variables’ definitions clearly.
