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

**How To Find The Slope Intercept Form With Two Points** – Among the many forms used to illustrate a linear equation one of the most frequently seen is the **slope intercept form**. You can use the formula of the slope-intercept identify a line equation when you have the slope of the straight line and the yintercept, which is the point’s y-coordinate at which the y-axis meets the line. Read more about this particular line equation form below.

## What Is The Slope Intercept Form?

There are three primary forms of linear equations, namely the standard one, the slope-intercept one, and the point-slope. Though they provide the same results , when used, you can extract the information line produced more quickly using the slope intercept form. Like the name implies, this form utilizes an inclined line, in which its “steepness” of the line is a reflection of its worth.

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

For the everyday world, the slope intercept form is frequently used to depict how an object or problem evolves over it’s course. The value that is provided by the vertical axis is a representation of how the equation addresses the degree of change over the value given by the horizontal axis (typically time).

A simple example of the application of this formula is to determine how many people live in a specific area in the course of time. In the event that the population in the area grows each year by a specific fixed amount, the amount of the horizontal line will increase one point at a moment each year and the point worth of the vertical scale is increased to represent the growing population according to the fixed amount.

You may also notice the starting point of a particular problem. The beginning value is located at the y-value of the y-intercept. The Y-intercept is the place at which x equals zero. Based on the example of a previous problem, the starting value would be at the time the population reading begins or when the time tracking starts along with the associated changes.

This is the place at which the population begins to be monitored to the researchers. Let’s suppose that the researcher began to perform the calculation or measure in the year 1995. This year will serve as”the “base” year, and the x = 0 point would occur in the year 1995. Thus, you could say 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 rate of change is represented in the form of the slope. The primary complication of this form is usually in the horizontal variable interpretation, particularly if the variable is accorded to one particular year (or any other kind number of units). The most important thing to do is to ensure that you understand the variables’ definitions clearly.
