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

**Slope Intercept To Point Slope Form** – Among the many forms used to illustrate a linear equation the one most commonly encountered is the **slope intercept form**. You can use the formula for the slope-intercept in order to solve a line equation as long as that you have the straight line’s slope and the y-intercept. This is the point’s y-coordinate where 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 traditional slope, slope-intercept and point-slope. Even though they can provide similar results when used however, you can get the information line produced more quickly through this slope-intercept form. It is a form that, as the name suggests, this form uses the sloped line and its “steepness” of the line indicates its value.

This formula can be used to find the slope of straight lines, the y-intercept or x-intercept where you can apply different formulas available. The equation for this line in this specific formula is **y = mx + b**. The slope of the straight line is indicated in the form of “m”, while its y-intercept is indicated via “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” are treated as variables.

## An Example of Applied Slope Intercept Form in Problems

The real-world in the real world, the slope intercept form is frequently used to depict how an object or problem changes in the course of time. The value provided by the vertical axis demonstrates how the equation tackles the magnitude of changes in the value given with the horizontal line (typically in the form of time).

An easy example of using this formula is to find out how much population growth occurs in a specific area in the course of time. In the event that the area’s population increases yearly by a predetermined amount, the worth of horizontal scale will rise one point at a moment for every passing year, and the amount of vertically oriented axis will rise in proportion to the population growth by the set amount.

You can also note the beginning value of a question. The starting value occurs at the y value in the yintercept. The Y-intercept marks the point at which x equals zero. Based on the example of a problem above, the starting value would be at the time the population reading begins or when time tracking starts, as well as the associated changes.

Thus, the y-intercept represents the point where the population starts to be monitored to the researchers. Let’s assume that the researcher begins to perform the calculation or measurement in the year 1995. The year 1995 would be”the “base” year, and the x = 0 point would be in 1995. Therefore, you can say that the 1995 population is the y-intercept.

Linear equation problems that use straight-line formulas are nearly always solved in this manner. The beginning value is depicted by the y-intercept and the rate of change is represented through the slope. The most significant issue with the slope-intercept form typically lies in the horizontal interpretation of the variable, particularly if the variable is accorded to a specific year (or any other type of unit). The first step to solve them is to ensure that you know the meaning of the variables.
