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

**Write An Equation In Slope Intercept Form 3** – Among the many forms employed to illustrate a linear equation the one most commonly used is the **slope intercept form**. It is possible to use the formula of the slope-intercept 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 intersects the line. Read more about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three fundamental forms of linear equations: the standard slope-intercept, the point-slope, and the standard. Even though they can provide identical results when utilized in conjunction, you can obtain the information line produced more efficiently by using the slope intercept form. It is a form that, as the name suggests, this form uses a sloped line in which its “steepness” of the line determines its significance.

This formula can be used to find the slope of a straight line. It is also known as y-intercept, or x-intercept, which can be calculated using a variety of formulas that are available. The equation for this line in this specific formula is **y = mx + b**. The slope of the straight line is represented by “m”, while its y-intercept is represented through “b”. Every point on the straight line is represented by 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 frequently used to illustrate how an item or issue evolves over an elapsed time. The value provided by the vertical axis demonstrates how the equation deals with the degree of change over the amount of time indicated with the horizontal line (typically times).

A basic example of this formula’s utilization is to figure out how much population growth occurs in a certain area as the years pass by. Using the assumption that the area’s population increases yearly by a certain amount, the values of the horizontal axis will rise one point at a moment with each passing year and the worth of the vertical scale will grow to represent the growing population by the fixed amount.

You may also notice the starting point of a question. The starting point is the y value in the yintercept. The Y-intercept marks the point where x is zero. By using the example of the above problem the beginning point could be when the population reading starts or when the time tracking starts along with the changes that follow.

So, the y-intercept is the location when the population is beginning to be documented for research. Let’s suppose that the researcher starts with the calculation or measurement in 1995. Then the year 1995 will become considered to be the “base” year, and the x = 0 points would be in 1995. So, it is possible to say that the population of 1995 is the y-intercept.

Linear equation problems that use straight-line formulas can be solved in this manner. The starting value is depicted by the y-intercept and the rate of change is represented as the slope. The main issue with the slope intercept form generally lies in the horizontal variable interpretation especially if the variable is associated with the specific year (or any type or unit). The most important thing to do is to make sure you know the variables’ definitions clearly.
