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

**Finding Slope Intercept Form** – One of the numerous forms employed to represent a linear equation, the one most commonly used is the **slope intercept form**. It is possible to use the formula for the slope-intercept in order to find a line equation assuming that you have the slope of the straight line and the y-intercept. This is the point’s y-coordinate at which the y-axis meets the line. Learn more about this particular line equation form below.

## What Is The Slope Intercept Form?

There are three main forms of linear equations: the standard, slope-intercept, and point-slope. Though they provide the same results , when used, you can extract the information line produced quicker using this slope-intercept form. Like the name implies, this form makes use of the sloped line and you can determine the “steepness” of the line is a reflection of its worth.

This formula can be used to calculate the slope of a straight line, the y-intercept (also known as the x-intercept), where you can apply different formulas available. The equation for a line using this specific formula is **y = mx + b**. The slope of the straight line is represented in the form of “m”, while its intersection with the y is symbolized via “b”. Every point on the straight line is represented with 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

In the real world in the real world, the slope intercept form is used frequently to depict how an object or issue evolves over its course. The value provided by the vertical axis demonstrates how the equation deals with the degree of change over the amount of time indicated via the horizontal axis (typically times).

A basic example of the use of this formula is to find out the rate at which population increases in a specific area as the years go by. In the event that the population of the area increases each year by a predetermined amount, the point worth of horizontal scale will increase one point at a moment for every passing year, and the point amount of vertically oriented axis will increase to reflect the increasing population by the set amount.

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

Thus, the y-intercept represents the location at which the population begins to be tracked for research. Let’s assume that the researcher began to do the calculation or the measurement in the year 1995. In this case, 1995 will serve as considered to be the “base” year, and the x = 0 point will occur in 1995. Thus, you could say that the population of 1995 will be the “y-intercept.

Linear equations that use straight-line formulas can be solved this way. The beginning value is represented by the y-intercept, and the rate of change is represented as the slope. The primary complication of the slope intercept form usually lies in the horizontal variable interpretation in particular when the variable is associated with the specific year (or any other type in any kind of measurement). The first step to solve them is to make sure you comprehend the variables’ definitions clearly.
