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

**Whats Slope Intercept Form** – Among the many forms that are used to represent a linear equation the one most frequently encountered is the **slope intercept form**. It is possible to use the formula of the slope-intercept to solve a line equation as long as that you have the slope of the straight line and the y-intercept, which is the y-coordinate of the point at the y-axis is intersected by the line. Learn more about this particular line equation form below.

## What Is The Slope Intercept Form?

There are three basic forms of linear equations, namely the standard slope-intercept, the point-slope, and the standard. While they all provide similar results when used, you can extract the information line produced quicker using the slope intercept form. The name suggests that this form uses an inclined line where you can determine the “steepness” of the line determines its significance.

This formula can be utilized to determine the slope of a straight line. It is also known as the y-intercept, also known as x-intercept where you can utilize a variety formulas that are available. The equation for this line in this particular formula is **y = mx + b**. The slope of the straight line is indicated with “m”, while its y-intercept is indicated with “b”. Each point of the straight line is represented with an (x, y). Note that in the y = mx + b equation formula, the “x” and the “y” are treated as variables.

## An Example of Applied Slope Intercept Form in Problems

In the real world in the real world, the slope-intercept form is often utilized to illustrate how an item or issue changes over its course. The value provided by the vertical axis demonstrates how the equation handles the extent of changes over the value provided by the horizontal axis (typically time).

One simple way to illustrate using this formula is to figure out how much population growth occurs in a certain area as time passes. Based on the assumption that the population in the area grows each year by a certain amount, the point value of the horizontal axis will increase by one point each year and the amount of vertically oriented axis will increase to represent the growing population by the amount fixed.

Also, you can note the beginning point of a problem. The beginning value is at the y value in the yintercept. The Y-intercept is the point at which x equals zero. In the case of the above problem the beginning point could be when the population reading starts or when the time tracking begins along with the related changes.

This is the point where the population starts to be recorded for research. Let’s suppose that the researcher is beginning with the calculation or take measurements in the year 1995. Then the year 1995 will become”the “base” year, and the x=0 points will be observed in 1995. So, it is possible to say that the population in 1995 is the y-intercept.

Linear equation problems that utilize straight-line formulas can be solved this way. The starting value is expressed by the y-intercept and the change rate is represented through the slope. The main issue with the slope-intercept form typically lies in the horizontal interpretation of the variable especially if the variable is linked to a specific year (or any other type of unit). The trick to overcoming them is to make sure you know the meaning of the variables.
