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

**Writing Equations In Slope Intercept Form** – Among the many forms that are used to illustrate a linear equation one that is commonly used is the **slope intercept form**. You may use the formula for the slope-intercept to identify a line equation when that you have the straight line’s slope and the y-intercept. This is the y-coordinate of the point at the y-axis intersects the line. Learn more about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three primary forms of linear equations: the traditional, slope-intercept, and point-slope. Though they provide similar results when used however, you can get the information line that is produced more efficiently with an equation that uses the slope-intercept form. It is a form that, as the name suggests, this form utilizes the sloped line and you can determine 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 formulas available. The line equation of this specific formula is **y = mx + b**. The straight line’s slope is indicated in the form of “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

When it comes to the actual world in the real world, the slope intercept form is often utilized to show how an item or problem changes in an elapsed time. The value of the vertical axis demonstrates how the equation tackles the degree of change over what is represented by the horizontal axis (typically in the form of time).

An easy example of this formula’s utilization is to discover 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 certain amount, the point value of the horizontal axis will rise one point at a moment as each year passes, and the point values of the vertical axis will rise to reflect the increasing population by the amount fixed.

It is also possible to note the beginning point of a particular problem. The beginning value is located at the y’s value within the y’intercept. The Y-intercept is the point where x is zero. If we take the example of a previous problem the beginning point could be at the time the population reading begins or when the time tracking starts, as well as the associated changes.

So, the y-intercept is the point in the population when the population is beginning to be monitored by the researcher. Let’s say that the researcher began with the calculation or measurement in the year 1995. In this case, 1995 will be the “base” year, and the x=0 points would occur in the year 1995. So, it is possible to say that the population of 1995 is the y-intercept.

Linear equations that employ straight-line equations are typically solved this way. The starting value is represented by the y-intercept, and the change rate is expressed in the form of the slope. The principal issue with this form is usually in the horizontal interpretation of the variable in particular when the variable is attributed to an exact year (or any type of unit). The most important thing to do is to ensure that you understand the meaning of the variables.
