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

**Slope-Intercept Form** – One of the numerous forms that are used to depict a linear equation, one of the most commonly used is the **slope intercept form**. It is possible to use the formula for the slope-intercept to determine a line equation, assuming you have the straight line’s slope and the y-intercept. This is the coordinate of the point’s y-axis where the y-axis is intersected by the line. Learn more about this specific linear equation form below.

## What Is The Slope Intercept Form?

There are three primary forms of linear equations: the traditional slope, slope-intercept and point-slope. Even though they can provide similar results when used however, you can get the information line that is produced faster through the slope-intercept form. Like the name implies, this form uses a sloped line in which the “steepness” of the line determines its significance.

This formula is able to calculate the slope of a straight line, the y-intercept, also known as x-intercept where you can utilize a variety available formulas. The equation for this line in this formula is **y = mx + b**. The straight line’s slope is indicated in the form of “m”, while its y-intercept is signified 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” need to remain 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 show how an item or problem evolves over its course. The value given by the vertical axis represents how the equation addresses the extent of changes over the amount of time indicated with the horizontal line (typically times).

A simple example of using this formula is to figure out how many people live in a certain area as the years go by. In the event that the population in the area grows each year by a fixed amount, the values of the horizontal axis increases one point at a moment with each passing year and the value of the vertical axis will grow to represent the growing population by the amount fixed.

Also, you can note the starting point of a problem. The starting point is the y value in the yintercept. The Y-intercept is the point where x is zero. If we take the example of the problem mentioned above the beginning point could be at the time the population reading starts or when the time tracking starts along with the associated changes.

Thus, the y-intercept represents the point that the population begins to be recorded in the research. Let’s say that the researcher is beginning to do the calculation or measure in the year 1995. Then the year 1995 will serve as the “base” year, and the x = 0 point would occur in the year 1995. Thus, you could say that the population of 1995 will be the “y-intercept.

Linear equation problems that use straight-line formulas can be solved in this manner. The starting value is expressed by the y-intercept and the rate of change is expressed as the slope. The primary complication of the slope intercept form typically lies in the horizontal interpretation of the variable especially if the variable is accorded to the specific year (or any type or unit). The most important thing to do is to ensure that you know the definitions of variables clearly.
