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

**Point Slope Form Into Slope Intercept Form** – One of the many forms used to illustrate a linear equation one that is frequently found is the **slope intercept form**. It is possible to use the formula of the slope-intercept find a line equation assuming that you have the slope of the straight line and the y-intercept, which is the y-coordinate of the point at the y-axis is intersected by the line. Learn more about this specific linear equation form below.

## What Is The Slope Intercept Form?

There are three primary forms of linear equations: the traditional, slope-intercept, and point-slope. Although they may not yield similar results when used, you can extract the information line produced more quickly with the slope-intercept form. As the name implies, this form employs a sloped line in which its “steepness” of the line determines its significance.

This formula can be utilized to determine the slope of straight lines, the y-intercept (also known as the x-intercept), where you can apply different formulas that are available. The line equation of this formula is **y = mx + b**. The straight line’s slope is represented in the form of “m”, while its y-intercept is signified by “b”. Every point on the straight line is represented by an (x, y). Note that in the y = mx + b equation formula, the “x” and the “y” need to remain 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 often utilized to illustrate how an item or problem evolves over the course of time. The value given by the vertical axis indicates how the equation addresses the extent of changes over the value given with the horizontal line (typically in the form of time).

One simple way to illustrate the use of this formula is to figure out how the population grows in a particular area as the years go by. If the area’s population increases yearly by a predetermined amount, the value of the horizontal axis will grow one point at a moment as each year passes, and the value of the vertical axis is increased to show the rising population by the set amount.

It is also possible to note the beginning point of a particular problem. The starting value occurs at the y value in the yintercept. The Y-intercept is the place at which x equals zero. In the case of a problem above, the starting value would be when the population reading begins or when time tracking begins , along with the associated changes.

This is the place that the population begins to be tracked to the researchers. Let’s assume that the researcher is beginning to do the calculation or measure in 1995. The year 1995 would be the “base” year, and the x = 0 point would be in 1995. This means that the population in 1995 corresponds to the y-intercept.

Linear equations that use straight-line formulas are almost always solved in this manner. The initial value is represented by the yintercept and the change rate is expressed in the form of the slope. The most significant issue with the slope intercept form typically lies in the horizontal variable interpretation in particular when the variable is attributed to an exact year (or any other kind of unit). The trick to overcoming them is to ensure that you comprehend the variables’ definitions clearly.
