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

**How To Find The B In Slope Intercept Form** – One of the many forms employed 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 straight line’s slope , and the y-intercept, which is the point’s y-coordinate at which the y-axis is intersected by the line. Learn more about this specific line equation form below.

## What Is The Slope Intercept Form?

There are three primary forms of linear equations: the standard one, the slope-intercept one, and the point-slope. Although they may not yield the same results , when used but you are able to extract the information line generated quicker through this slope-intercept form. As the name implies, this form employs the sloped line and you can determine the “steepness” of the line is a reflection of its worth.

The formula can be used to determine the slope of straight lines, the y-intercept (also known as the x-intercept), in which case you can use a variety of available formulas. The line equation of this formula is **y = mx + b**. The slope of the straight line is represented through “m”, while its y-intercept is indicated through “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” must remain as variables.

## An Example of Applied Slope Intercept Form in Problems

For the everyday world in the real world, the slope intercept form is often utilized to illustrate how an item or issue evolves over its course. The value of the vertical axis indicates how the equation addresses the extent of changes over the value provided via the horizontal axis (typically the time).

One simple way to illustrate using this formula is to determine how much population growth occurs in a certain area as time passes. Using the assumption that the population in the area grows each year by a fixed amount, the values of the horizontal axis increases one point at a moment for every passing year, and the value of the vertical axis is increased to reflect the increasing population according to the fixed amount.

You may also notice the starting value of a question. The starting point is the y value in the yintercept. The Y-intercept is the place where x is zero. In the case of a previous problem the starting point would be when the population reading begins or when the time tracking starts along with the changes that follow.

So, the y-intercept is the point that the population begins to be monitored for research. Let’s assume that the researcher begins to do the calculation or measure in 1995. In this case, 1995 will become considered to be the “base” year, and the x 0 points would be in 1995. This means that the population of 1995 corresponds to the y-intercept.

Linear equations that use straight-line formulas are nearly always solved this way. The initial value is expressed by the y-intercept and the rate of change is represented by the slope. The primary complication of the slope-intercept form typically lies in the interpretation of horizontal variables particularly when the variable is linked to the specific year (or any other type or unit). The trick to overcoming them is to make sure you know the meaning of the variables.
