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

**What Is The Equation Of The Line In Slope-Intercept Form** – One of the many forms used to represent a linear equation among the ones most 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 straight line’s slope as well as the y-intercept, which is the point’s y-coordinate at which the y-axis crosses the line. Find out more information about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three fundamental forms of linear equations: standard, slope-intercept, and point-slope. Although they may not yield the same results when utilized, you can extract the information line that is produced quicker through this slope-intercept form. It is a form that, as the name suggests, this form makes use of the sloped line and the “steepness” of the line is a reflection of its worth.

This formula is able to find the slope of a straight line. It is also known as the y-intercept (also known as the x-intercept), in which case you can use a variety of available formulas. The equation for a line using this specific formula is **y = mx + b**. The slope of the straight line is represented through “m”, while its intersection with the y is symbolized with “b”. Each point of the straight line is represented by 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

For the everyday world, the slope intercept form is frequently used to illustrate how an item or issue evolves over the course of time. The value of the vertical axis indicates how the equation addresses the extent of changes over the value given through the horizontal axis (typically time).

One simple way to illustrate using this formula is to discover the rate at which population increases in a certain area as the years go by. If the population of the area increases each year by a specific fixed amount, the amount of the horizontal line will increase by a single point as each year passes, and the point values of the vertical axis is increased to show the rising population by the set amount.

You can also note the starting value of a problem. The beginning value is at the y’s value within the y’intercept. The Y-intercept is the point at which x equals zero. In the case of the problem mentioned above the beginning value will be when the population reading begins or when time tracking begins , along with the related changes.

This is the place where the population starts to be recorded for research. Let’s say that the researcher began to calculate or take measurements in 1995. In this case, 1995 will represent the “base” year, and the x = 0 points would occur in the year 1995. This means that the 1995 population corresponds to the y-intercept.

Linear equations that employ straight-line formulas are almost always solved this way. The initial value is represented by the yintercept and the change rate is expressed in the form of the slope. The primary complication of the slope-intercept form usually lies in the interpretation of horizontal variables especially if the variable is attributed to one particular year (or any other type of unit). The key to solving them is to make sure you know the meaning of the variables.
