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

**Slope Intercept Form Calculator With One Point And Slope** – One of the numerous forms used to depict a linear equation, one that is frequently used is the **slope intercept form**. The formula for the slope-intercept to identify a line equation when 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 crosses the line. Learn more about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three main forms of linear equations: the standard slope, slope-intercept and point-slope. Even though they can provide identical results when utilized, you can extract the information line more efficiently with the slope-intercept form. Like the name implies, this form uses an inclined line, in which you can determine the “steepness” of the line determines its significance.

This formula can be used to determine the slope of straight lines, y-intercept, or x-intercept, in which case you can use a variety of formulas that are available. The line equation of this specific formula is **y = mx + b**. The slope of the straight line is symbolized with “m”, while its y-intercept is signified by “b”. Each point of the straight line is represented as 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

The real-world, the slope intercept form is used frequently to depict how an object or problem changes in it’s course. The value of the vertical axis demonstrates how the equation addresses the degree of change over the value given via the horizontal axis (typically time).

An easy example of the use of this formula is to determine how many people live within a specific region as the years go by. Using the assumption that the population of the area increases each year by a fixed amount, the point amount of the horizontal line will grow one point at a time each year and the amount of vertically oriented axis will rise to show the rising population by the set amount.

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

This is the place when the population is beginning to be monitored for research. Let’s say that the researcher is beginning to perform the calculation or take measurements in the year 1995. This year will represent considered to be the “base” year, and the x 0 points would occur in the year 1995. So, it is possible to say that the 1995 population corresponds to the y-intercept.

Linear equations that use straight-line formulas can be solved in this manner. The starting point is depicted by the y-intercept and the change rate is represented through the slope. The primary complication of this form generally lies in the horizontal variable interpretation particularly when the variable is accorded to a specific year (or any type of unit). The trick to overcoming them is to make sure you are aware of the meaning of the variables.
