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

**Find Slope Intercept Form With Two Points** – One of the many forms that are used to represent a linear equation one of the most frequently encountered 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 straight line’s slope as well as the y-intercept, which is the point’s y-coordinate where the y-axis meets the line. Learn more about this particular line equation form below.

## What Is The Slope Intercept Form?

There are three primary forms of linear equations: standard slope-intercept, the point-slope, and the standard. Though they provide the same results when utilized but you are able to extract the information line generated more quickly through the slope intercept form. Like the name implies, this form utilizes a sloped line in which you can determine the “steepness” of the line indicates its value.

This formula can be utilized to find the slope of straight lines, the y-intercept or x-intercept which can be calculated using a variety of available formulas. The line equation of this particular formula is **y = mx + b**. The slope of the straight line is symbolized in the form of “m”, while its y-intercept is represented by “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 used frequently to show how an item or problem changes in it’s course. The value of the vertical axis demonstrates how the equation handles the intensity of changes over the amount of time indicated through the horizontal axis (typically the time).

A basic example of using this formula is to find out the rate at which population increases in a certain area as the years go by. Based on the assumption that the population in the area grows each year by a predetermined amount, the values of the horizontal axis will rise by one point for every passing year, and the values of the vertical axis will grow to reflect the increasing population by the fixed amount.

Also, you can note the starting point of a question. The starting point is the y-value of the y-intercept. The Y-intercept represents the point where x is zero. In the case of a previous problem the starting point would be at the time the population reading begins or when time tracking starts along with the changes that follow.

This is the location that the population begins to be monitored by the researcher. Let’s suppose that the researcher is beginning to do the calculation or the measurement in 1995. Then the year 1995 will serve as the “base” year, and the x = 0 point would be in 1995. Thus, you could say that the population in 1995 corresponds to the y-intercept.

Linear equation problems that use straight-line formulas can be solved in this manner. The starting point is represented by the y-intercept, and the rate of change is expressed as the slope. The primary complication of this form is usually in the horizontal interpretation of the variable, particularly if the variable is linked to an exact year (or any other type of unit). The first step to solve them is to make sure you comprehend the variables’ definitions clearly.
