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

**Define Slope Intercept Form** – One of the many forms used to represent a linear equation, one of the most frequently found is the **slope intercept form**. You can use the formula of the slope-intercept to determine a line equation, assuming you have the straight line’s slope and the yintercept, which is the point’s y-coordinate where 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: the traditional slope, slope-intercept and point-slope. Although they may not yield the same results when utilized however, you can get the information line generated more quickly by using an equation that uses the slope-intercept form. The name suggests that this form uses an inclined line where its “steepness” of the line indicates its value.

This formula can be utilized to determine the slope of a straight line, y-intercept, or x-intercept, where you can utilize a variety available formulas. The equation for this line in this specific formula is **y = mx + b**. The straight line’s slope is symbolized by “m”, while its y-intercept is indicated via “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” 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 commonly used to represent how an item or issue changes over its course. The value that is provided by the vertical axis demonstrates how the equation tackles the magnitude of changes in the value provided with the horizontal line (typically the time).

A basic example of using this formula is to discover how much population growth occurs in a specific area as time passes. Using the assumption that the population of the area increases each year by a predetermined amount, the point value of the horizontal axis will increase one point at a moment with each passing year and the point amount of vertically oriented axis will grow to represent the growing population according to the fixed amount.

You can also note the beginning value of a challenge. The starting point is the y-value of the y-intercept. The Y-intercept is the point where x is zero. Based on the example of the problem mentioned above, the starting value would be at the point when the population reading begins or when the time tracking starts along with the related changes.

The y-intercept, then, is the place at which the population begins to be monitored to the researchers. Let’s say that the researcher is beginning with the calculation or the measurement in the year 1995. The year 1995 would represent”the “base” year, and the x = 0 point would be in 1995. This means that the population of 1995 represents the “y”-intercept.

Linear equations that use straight-line formulas are almost always solved this way. The beginning value is represented by the yintercept and the rate of change is represented through the slope. The principal issue with the slope intercept form typically lies in the horizontal variable interpretation especially if the variable is associated with one particular year (or any other type in any kind of measurement). The first step to solve them is to ensure that you know the variables’ definitions clearly.
