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

**Solving Slope Intercept Form** – There are many forms employed to depict a linear equation, one of the most commonly used is the **slope intercept form**. You may use the formula of the slope-intercept to find a line equation assuming that you have the slope of the straight line and the yintercept, which is the point’s y-coordinate where the y-axis is intersected by the line. Find out more information about this particular line equation form below.

## What Is The Slope Intercept Form?

There are three basic forms of linear equations: standard, slope-intercept, and point-slope. Even though they can provide the same results when utilized, you can extract the information line generated faster through the slope intercept form. Like the name implies, this form utilizes a sloped line in which the “steepness” of the line is a reflection of its worth.

This formula is able to find the slope of a straight line. It is also known as the y-intercept or x-intercept which can be calculated using a variety of available formulas. The line equation in this formula is **y = mx + b**. The straight line’s slope is signified through “m”, while its y-intercept is indicated with “b”. Each point of the straight line is represented as 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, the slope intercept form is often utilized to illustrate how an item or issue evolves over the course of time. The value that is provided by the vertical axis is a representation of how the equation tackles the intensity of changes over the value provided through the horizontal axis (typically times).

An easy example of using this formula is to figure out the rate at which population increases in a particular area as the years pass by. Based on the assumption that the population of the area increases each year by a specific fixed amount, the point value of the horizontal axis will rise one point at a moment each year and the worth of the vertical scale will rise in proportion to the population growth according to the fixed amount.

You can also note the starting value of a particular problem. The beginning value is located at 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 point could be when the population reading starts or when the time tracking begins , along with the changes that follow.

So, the y-intercept is the point where the population starts to be monitored in the research. Let’s suppose that the researcher began to perform the calculation or take measurements in the year 1995. The year 1995 would serve as”the “base” year, and the x 0 points will be observed in 1995. This means that the population of 1995 is the y-intercept.

Linear equation problems that use straight-line formulas can be solved this way. The starting point is represented by the yintercept and the rate of change is expressed by the slope. The primary complication of this form usually lies in the horizontal interpretation of the variable especially if the variable is accorded to the specific year (or any type in any kind of measurement). The most important thing to do is to make sure you know the variables’ definitions clearly.
