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

**Slope Intercept Form From 2 Points** – One of the many forms employed to depict a linear equation, the one most commonly seen is the **slope intercept form**. The formula for the slope-intercept in order to identify a line equation when you have the slope of the straight line and the y-intercept. It is the point’s y-coordinate at which the y-axis crosses the line. Find out more information about this particular line equation form below.

## What Is The Slope Intercept Form?

There are three basic forms of linear equations: the traditional slope, slope-intercept and point-slope. Even though they can provide the same results when utilized, you can extract the information line faster through the slope intercept form. As the name implies, this form utilizes an inclined line, in which the “steepness” of the line determines its significance.

This formula can be used to discover the slope of straight lines, the y-intercept, also known as x-intercept where you can utilize a variety formulas that are available. The equation for a line using this formula is **y = mx + b**. The slope of the straight line is signified in the form of “m”, while its y-intercept is represented with “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” 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 used frequently to depict how an object or issue evolves over it’s course. The value given by the vertical axis is a representation of how the equation tackles the degree of change over what is represented via the horizontal axis (typically time).

A simple example of using this formula is to figure out how much population growth occurs within a specific region in the course of time. Based on the assumption that the population of the area increases each year by a predetermined amount, the values of the horizontal axis will increase one point at a time as each year passes, and the point amount of vertically oriented axis will increase to show the rising population according to the fixed amount.

It is also possible to note the starting value of a question. The beginning value is located at the y value in the yintercept. The Y-intercept is the place at which x equals zero. If we take the example of the problem mentioned above the beginning point could be at the time the population reading begins or when the time tracking starts along with the related changes.

The y-intercept, then, is the point where the population starts to be recorded by the researcher. Let’s suppose that the researcher begins to do the calculation or take measurements in 1995. This year will represent”the “base” year, and the x=0 points will occur in 1995. So, it is possible to say that the 1995 population represents the “y”-intercept.

Linear equation problems that utilize straight-line formulas are almost always solved in this manner. The initial value is expressed by the y-intercept and the change rate is expressed through the slope. The main issue with the slope-intercept form generally lies in the horizontal interpretation of the variable especially if the variable is associated with the specific year (or any type or unit). The key to solving them is to ensure that you comprehend the variables’ definitions clearly.
