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

**In General Form** – Among the many forms employed to depict a linear equation, one of the most frequently used is the **slope intercept form**. It is possible to use the formula for the slope-intercept to solve a line equation as long as you have the slope of the straight line and the y-intercept. It is the coordinate of the point’s y-axis where the y-axis crosses the line. Find out more information about this particular line equation form below.

## What Is The Slope Intercept Form?

There are three main forms of linear equations: standard one, the slope-intercept one, and the point-slope. Though they provide similar results when used but you are able to extract the information line generated more quickly using the slope-intercept form. The name suggests that this form employs an inclined line where it is the “steepness” of the line determines its significance.

This formula can be used to calculate the slope of a straight line, the y-intercept (also known as the x-intercept), in which case you can use a variety of available formulas. The equation for a line using this specific formula is **y = mx + b**. The slope of the straight line is symbolized by “m”, while its y-intercept is represented through “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” must remain as variables.

## An Example of Applied Slope Intercept Form in Problems

When it comes to the actual world in the real world, the slope intercept form is commonly used to show how an item or problem evolves over the course of time. The value that is provided by the vertical axis demonstrates how the equation handles the magnitude of changes in the value given through the horizontal axis (typically times).

An easy example of using this formula is to discover how much population growth occurs in a particular area in the course of time. In the event that the population of the area increases each year by a predetermined amount, the point worth of horizontal scale will grow by a single point as each year passes, and the point values of the vertical axis will grow to represent the growing population according to the fixed amount.

You can also note the starting point of a challenge. The beginning value is at the y-value in the y-intercept. The Y-intercept is the place where x is zero. By using the example of a problem above the beginning point could be at the point when the population reading begins or when the time tracking begins , along with the related changes.

This is the point in the population where the population starts to be recorded by the researcher. Let’s assume that the researcher began to perform the calculation or measurement in 1995. The year 1995 would become the “base” year, and the x = 0 points would occur in the year 1995. Thus, you could say that the 1995 population is the y-intercept.

Linear equation problems that utilize straight-line equations are typically solved in this manner. The starting point is represented by the y-intercept, and the change rate is expressed as the slope. The most significant issue with the slope-intercept form usually lies in the horizontal variable interpretation, particularly if the variable is associated with one particular year (or any kind in any kind of measurement). The most important thing to do is to make sure you understand the variables’ meanings in detail.
