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

**What Is An Equation Of The Line In Slope Intercept Form Y=2x-2** – Among the many forms used to depict a linear equation, the one most commonly found is the **slope intercept form**. You can use the formula for the slope-intercept to identify a line equation when you have the slope of the straight line and the y-intercept. This is the point’s y-coordinate at which the y-axis is intersected by the line. Learn more about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three basic forms of linear equations: the traditional, slope-intercept, and point-slope. Though they provide the same results , when used in conjunction, you can obtain the information line generated faster through the slope-intercept form. It is a form that, as the name suggests, this form utilizes a sloped line in which it is the “steepness” of the line indicates its value.

This formula can be used to calculate the slope of a straight line, the y-intercept, also known as x-intercept which can be calculated using a variety of formulas available. The line equation of this formula is **y = mx + b**. The straight line’s slope is represented by “m”, while its intersection with the y is symbolized with “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” must remain as variables.

## An Example of Applied Slope Intercept Form in Problems

For the everyday world in the real world, the slope intercept form is commonly used to represent how an item or problem changes in an elapsed time. The value of the vertical axis represents how the equation tackles the intensity of changes over the value given through the horizontal axis (typically the time).

A basic example of the application of this formula is to find out how the population grows in a particular area as the years go by. In the event that the area’s population grows annually by a certain amount, the point value of the horizontal axis increases one point at a moment as each year passes, and the point amount of vertically oriented axis will increase to show the rising population by the set amount.

You may also notice the starting point of a question. The beginning value is located at the y’s value within the y’intercept. The Y-intercept marks the point where x is zero. By using the example of a previous problem the starting point would be the time when the reading of population begins or when the time tracking begins , along with the changes that follow.

This is the point at which the population begins to be recorded for research. Let’s assume that the researcher is beginning to do the calculation or measure in the year 1995. This year will become the “base” year, and the x=0 points will be observed in 1995. So, it is possible to say that the population in 1995 represents the “y”-intercept.

Linear equation problems that utilize straight-line equations are typically solved this way. The initial value is represented by the yintercept and the change rate is represented by the slope. The primary complication of the slope-intercept form generally lies in the horizontal interpretation of the variable, particularly if the variable is linked to a specific year (or any other type of unit). The first step to solve them is to make sure you are aware of the variables’ meanings in detail.
