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

**How To Turn An Equation Into Slope Intercept Form** – There are many forms employed to illustrate a linear equation among the ones most commonly encountered is the **slope intercept form**. You can use the formula for the slope-intercept in order to determine a line equation, assuming you have the straight line’s slope , and the y-intercept. This is the point’s y-coordinate at which 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, namely the standard slope, slope-intercept and point-slope. Though they provide identical results when utilized however, you can get the information line more efficiently using an equation that uses the slope-intercept form. The name suggests that this form uses a sloped line in which it is the “steepness” of the line is a reflection of its worth.

The formula can be used to find the slope of a straight line, y-intercept, or x-intercept, in which case you can use a variety of formulas that are available. The line equation in this formula is **y = mx + b**. The slope of the straight line is symbolized in the form of “m”, while its y-intercept is indicated via “b”. Every point on the straight line is represented as 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

In the real world in the real world, the slope intercept form is commonly used to show how an item or problem evolves over it’s course. The value provided by the vertical axis is a representation of how the equation deals with the extent of changes over the value given by the horizontal axis (typically the time).

One simple way to illustrate the use of this formula is to discover how many people live in a specific area as the years go by. If the area’s population grows annually by a predetermined amount, the amount of the horizontal line will increase by a single point with each passing year and the values of the vertical axis will grow to reflect the increasing population according to the fixed amount.

Also, you can note the beginning point of a problem. The beginning value is located at the y value in the yintercept. The Y-intercept is the place where x is zero. Based on the example of a previous problem the starting point would be when the population reading starts or when the time tracking starts along with the related changes.

So, the y-intercept is the place that the population begins to be tracked to the researchers. Let’s say that the researcher began to do the calculation or measurement in the year 1995. In this case, 1995 will become considered to be the “base” year, and the x = 0 points will occur in 1995. So, it is possible to say that the population in 1995 is the y-intercept.

Linear equations that use straight-line formulas are nearly always solved this way. The starting point is represented by the yintercept and the rate of change is expressed in the form of the slope. The principal issue with an interceptor slope form generally lies in the interpretation of horizontal variables, particularly if the variable is accorded to the specific year (or any other type number of units). The key to solving them is to ensure that you are aware of the variables’ meanings in detail.
