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

Definition Of Slope Intercept Form – Among the many forms used to represent a linear equation among the ones most commonly encountered is the slope intercept form. The formula for the slope-intercept to find a line equation assuming that you have the slope of the straight line and the yintercept, which is the point’s y-coordinate where the y-axis crosses the line. Learn more about this specific linear equation form below.

What Is The Slope Intercept Form?

There are three fundamental forms of linear equations: the standard slope, slope-intercept and point-slope. Even though they can provide similar results when used in conjunction, you can obtain the information line produced more efficiently with an equation that uses the slope-intercept form. Like the name implies, this form utilizes an inclined line where the “steepness” of the line reflects its value.

The formula can be used to discover the slope of straight lines, the y-intercept (also known as the x-intercept), where you can apply different formulas available. The line equation in this specific formula is y = mx + b. The straight line’s slope is symbolized by “m”, while its y-intercept is signified via “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” 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 used frequently to illustrate how an item or issue evolves over the course of time. The value provided by the vertical axis is a representation of how the equation addresses the intensity of changes over what is represented through the horizontal axis (typically the time).

A basic example of this formula’s utilization is to determine how much population growth occurs within a specific region in the course of time. If the area’s population increases yearly by a fixed amount, the point amount of the horizontal line increases by one point as each year passes, and the amount of vertically oriented axis is increased in proportion to the population growth by the amount fixed.

Also, you can note the beginning point of a problem. The starting point is the y’s value within the y’intercept. The Y-intercept is the place at which x equals zero. By using the example of the problem mentioned above the starting point would be at the time the population reading starts or when the time tracking begins along with the changes that follow.

Thus, the y-intercept represents the location where the population starts to be documented by the researcher. Let’s say that the researcher starts to calculate or measurement in the year 1995. This year will become”the “base” year, and the x = 0 point would be in 1995. So, it is possible to say that the 1995 population will be the “y-intercept.

Linear equation problems that utilize straight-line formulas can be solved this way. The initial value is expressed by the y-intercept and the change rate is expressed through the slope. The principal issue with the slope intercept form generally lies in the horizontal interpretation of the variable particularly when the variable is accorded to a specific year (or any type of unit). The trick to overcoming them is to ensure that you know the variables’ meanings in detail.
