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

**Graph Slope Intercept Form Calculator** – There are many forms used to represent a linear equation one that is commonly seen is the **slope intercept form**. You may use the formula of the slope-intercept to determine a line equation, assuming that you have the slope of the straight line and the y-intercept. It is the point’s y-coordinate where 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: the traditional slope-intercept, the point-slope, and the standard. While they all provide the same results , when used however, you can get the information line produced faster using this slope-intercept form. It is a form that, as the name suggests, this form employs an inclined line, in which it is the “steepness” of the line indicates its value.

This formula is able to determine the slope of straight lines, the y-intercept (also known as the x-intercept), where you can apply different available formulas. The line equation in this specific formula is **y = mx + b**. The slope of the straight line is indicated by “m”, while its y-intercept is indicated through “b”. Every point on the straight line is represented as an (x, y). Note that in the y = mx + b equation formula the “x” and the “y” have to remain as 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 illustrate how an item or problem evolves over an elapsed time. The value provided by the vertical axis is a representation of how the equation deals with the intensity of changes over what is represented through the horizontal axis (typically time).

A basic example of the application of this formula is to determine the rate at which population increases within a specific region as time passes. Based on the assumption that the population of the area increases each year by a fixed amount, the point value of the horizontal axis will grow one point at a moment as each year passes, and the point values of the vertical axis will grow to reflect the increasing population according to the fixed amount.

You can also note the starting point of a question. The beginning value is located at the y-value in the y-intercept. The Y-intercept is the point at which x equals zero. By using the example of the problem mentioned above the beginning value will be the time when the reading of population starts or when the time tracking begins , along with the changes that follow.

The y-intercept, then, is the location at which the population begins to be recorded in the research. Let’s assume that the researcher began to perform the calculation or the measurement in the year 1995. The year 1995 would represent”the “base” year, and the x 0 points will be observed in 1995. This means that the population in 1995 corresponds to the y-intercept.

Linear equations that employ straight-line formulas are almost always solved this way. The starting value is expressed by the y-intercept and the change rate is expressed in the form of the slope. The main issue with the slope-intercept form generally lies in the interpretation of horizontal variables especially if the variable is linked to a specific year (or any other kind of unit). The key to solving them is to make sure you understand the variables’ meanings in detail.
