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

**How To Find Slope Intercept Form From Two Points** – One of the many forms that are used to depict a linear equation, one that is commonly found is the **slope intercept form**. The formula for the slope-intercept in order to determine a line equation, assuming you have the straight line’s slope and the y-intercept. It is the coordinate of the point’s y-axis where 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 basic forms of linear equations, namely the standard, slope-intercept, and point-slope. Though they provide the same results , when used but you are able to extract the information line more efficiently with an equation that uses the slope-intercept form. Like the name implies, this form employs an inclined line where it is the “steepness” of the line determines its significance.

This formula can be used to calculate a straight line’s slope, y-intercept, or x-intercept, which can be calculated using a variety of formulas that are available. The equation for this line in this particular formula is **y = mx + b**. The straight line’s slope is symbolized by “m”, while its intersection with the y is symbolized with “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” need to remain 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 represent how an item or problem changes in it’s course. The value given by the vertical axis is a representation of how the equation deals with the intensity of changes over the value provided with the horizontal line (typically the time).

A simple example of the use of this formula is to discover how the population grows within a specific region as the years go by. If the area’s population grows annually by a certain amount, the point amount of the horizontal line will increase one point at a moment with each passing year and the values of the vertical axis will rise to represent the growing population by the fixed amount.

Also, you can note the beginning point of a question. The beginning value is located at the y-value in the y-intercept. 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 starts along with the related changes.

This is the place at which the population begins to be documented for research. Let’s assume that the researcher is beginning to perform the calculation or take measurements in the year 1995. In this case, 1995 will become”the “base” year, and the x 0 points would occur in the year 1995. This means that the population in 1995 corresponds to the y-intercept.

Linear equation problems that use straight-line equations are typically solved this way. The starting value is represented by the yintercept and the change rate is expressed by the slope. The primary complication of this form usually lies in the horizontal interpretation of the variable especially if the variable is linked to one particular year (or any other kind number of units). The first step to solve them is to make sure you understand the meaning of the variables.
