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

**How To Solve For B In Slope Intercept Form** – Among the many forms used to illustrate a linear equation one of the most commonly seen is the **slope intercept form**. It is possible to use the formula for the slope-intercept in order to determine a line equation, assuming 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 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: standard slope, slope-intercept and point-slope. Even though they can provide similar results when used however, you can get the information line produced faster by using this slope-intercept form. Like the name implies, this form utilizes an inclined line where its “steepness” of the line determines its significance.

This formula can be used to calculate the slope of a straight line, the y-intercept or x-intercept where you can utilize a variety formulas available. The equation for this line in this formula is **y = mx + b**. The slope of the straight line is represented with “m”, while its y-intercept is signified by “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” need to remain variables.

## An Example of Applied Slope Intercept Form in Problems

When it comes to the actual world in the real world, the slope-intercept form is commonly used to represent how an item or problem evolves over it’s course. The value of the vertical axis indicates how the equation deals with the extent of changes over the value provided through the horizontal axis (typically time).

One simple way to illustrate using this formula is to figure out the rate at which population increases in a certain area as the years pass by. If the population of the area increases each year by a specific fixed amount, the value of the horizontal axis will increase by one point with each passing year and the point worth of the vertical scale is increased in proportion to the population growth by the fixed amount.

Also, you can note the beginning point of a challenge. The starting point is the y’s value within the y’intercept. The Y-intercept marks the point at which x equals zero. In the case of a problem above the beginning point could be the time when the reading of population begins or when time tracking begins along with the changes that follow.

Thus, the y-intercept represents the location that the population begins to be tracked for research. Let’s assume that the researcher is beginning to calculate or measurement in the year 1995. This year will be”the “base” year, and the x = 0 points would occur in the year 1995. So, it is possible to say that the population in 1995 corresponds to the y-intercept.

Linear equation problems that utilize straight-line formulas can be solved this way. The starting value is depicted by the y-intercept and the rate of change is expressed as the slope. The primary complication of this form generally lies in the horizontal variable interpretation especially if the variable is associated with an exact year (or any other kind of unit). The most important thing to do is to ensure that you understand the variables’ meanings in detail.
