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

**Slope Intercept Form Linear Equation** – Among the many forms employed to illustrate a linear equation one of the most frequently found is the **slope intercept form**. It is possible to use the formula of the slope-intercept to determine a line equation, assuming you have the slope of the straight line and the y-intercept. This is the point’s y-coordinate at which the y-axis intersects the line. Find out more information about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three primary forms of linear equations, namely the standard slope, slope-intercept and point-slope. Although they may not yield the same results , when used but you are able to extract the information line generated quicker through this slope-intercept form. Like the name implies, this form utilizes an inclined line where the “steepness” of the line indicates its value.

This formula can be used to find the slope of a straight line. It is also known as the y-intercept (also known as the x-intercept), which can be calculated using a variety of formulas that are available. The equation for this line in this particular formula is **y = mx + b**. The straight line’s slope is represented through “m”, while its y-intercept is indicated with “b”. Each point of the straight line can be represented using 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 represent how an item or problem evolves over an elapsed time. The value given by the vertical axis represents how the equation addresses the magnitude of changes in the amount of time indicated through the horizontal axis (typically time).

A basic example of using this formula is to figure out how much population growth occurs in a certain area as the years go by. Using the assumption that the area’s population increases yearly by a specific fixed amount, the point value of the horizontal axis will grow by a single point each year and the values of the vertical axis is increased to show the rising population by the fixed amount.

Also, you can note the beginning value of a challenge. The starting point is the y’s value within the y’intercept. The Y-intercept is the place where x is zero. In the case of a previous problem the starting point would be the time when the reading of population begins or when the time tracking starts, as well as the associated changes.

The y-intercept, then, is the point that the population begins to be monitored to the researchers. Let’s say that the researcher began with the calculation or measurement in the year 1995. In this case, 1995 will serve as”the “base” year, and the x = 0 point would occur in the year 1995. This means that the population in 1995 will be the “y-intercept.

Linear equations that employ straight-line equations are typically solved in this manner. The initial value is represented by the y-intercept, and the change rate is expressed through the slope. The main issue with an interceptor slope form usually lies in the interpretation of horizontal variables especially if the variable is attributed to a specific year (or any kind number of units). The key to solving them is to make sure you understand the definitions of variables clearly.
