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

**Slope Intercept Form Equations** – Among the many forms that are used to depict a linear equation, one that is frequently found is the **slope intercept form**. You can use the formula of the slope-intercept determine a line equation, assuming that you have the slope of the straight line and the yintercept, which is the point’s y-coordinate where the y-axis is intersected by 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: standard, slope-intercept, and point-slope. Even though they can provide the same results when utilized but you are able to extract the information line generated quicker through the slope intercept form. It is a form that, as the name suggests, this form utilizes an inclined line, in which its “steepness” of the line reflects its value.

This formula is able to discover 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 line equation in this specific formula is **y = mx + b**. The slope of the straight line is represented by “m”, while its intersection with the y is symbolized by “b”. Each point of the straight line can be represented using 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

The real-world in the real world, the slope-intercept form is commonly used to depict how an object or issue changes over an elapsed time. The value that is provided by the vertical axis indicates how the equation deals with the intensity of changes over the value given through the horizontal axis (typically in the form of time).

One simple way to illustrate using this formula is to figure out how the population grows in a particular area as the years go by. If the area’s population grows annually by a fixed amount, the point worth of horizontal scale will increase one point at a time with each passing year and the amount of vertically oriented axis will rise in proportion to the population growth according to the fixed amount.

It is also possible to note the beginning point of a particular problem. The starting point is the y’s value within the y’intercept. The Y-intercept is the place where x is zero. By using the example of the problem mentioned above, the starting value would be the time when the reading of population begins or when time tracking starts along with the associated changes.

So, the y-intercept is the place at which the population begins to be monitored to the researchers. Let’s say that the researcher starts to do the calculation or take measurements in the year 1995. This year will be considered to be the “base” year, and the x = 0 points will occur in 1995. This means that the population of 1995 represents the “y”-intercept.

Linear equations that use straight-line formulas can be solved in this manner. The beginning value is depicted by the y-intercept and the change rate is expressed as the slope. The primary complication of the slope intercept form generally lies in the horizontal interpretation of the variable in particular when the variable is associated with the specific year (or any other type number of units). The most important thing to do is to ensure that you comprehend the variables’ meanings in detail.
