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

**How To Find Slope Intercept Form With 2 Points** – Among the many forms used to depict a linear equation, one that is commonly used is the **slope intercept form**. You may use the formula for the slope-intercept to find a line equation assuming that you have the slope of the straight line and the y-intercept, which is the coordinate of the point’s y-axis where the y-axis crosses the line. Read more about this particular linear equation form below.

## What Is The Slope Intercept Form?

There are three main forms of linear equations: the standard one, the slope-intercept one, and the point-slope. Although they may not yield the same results when utilized in conjunction, you can obtain the information line produced more quickly using the slope intercept form. As the name implies, this form makes use of the sloped line and it is the “steepness” of the line indicates its value.

This formula can be used to determine the slope of straight lines, y-intercept, or x-intercept, where you can utilize a variety available formulas. The equation for a line using this formula is **y = mx + b**. The straight line’s slope is represented by “m”, while its y-intercept is represented with “b”. Every point on the straight line is represented by 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

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

A simple example of this formula’s utilization is to discover how much population growth occurs in a certain area as the years pass by. If the area’s population grows annually by a fixed amount, the point values of the horizontal axis will grow by a single point each year and the point values of the vertical axis will rise to reflect the increasing population by the fixed amount.

You may also notice the beginning point of a problem. The starting value occurs at the y-value of the y-intercept. The Y-intercept represents the point at which x equals zero. If we take the example of the problem mentioned above the beginning value will be at the point when the population reading begins or when the time tracking begins along with the changes that follow.

The y-intercept, then, is the place when the population is beginning to be recorded in the research. Let’s suppose that the researcher starts with the calculation or measure in the year 1995. The year 1995 would represent”the “base” year, and the x=0 points would be in 1995. So, it is possible to say that the population of 1995 will be the “y-intercept.

Linear equations that employ straight-line formulas are nearly always solved in this manner. The starting value is represented by the yintercept and the rate of change is represented through the slope. The most significant issue with the slope-intercept form typically lies in the horizontal variable interpretation in particular when the variable is attributed to one particular year (or any other kind or unit). The first step to solve them is to make sure you understand the variables’ meanings in detail.
