Slope Formula: Slope = (Y2 - Y1)/(X2 - X1)

Slope Definition
Calculating the slope of a line is a cinch with our online slope calculator. It’s quick, easy and takes but a moment to do because you only need to enter the x and y coordinates of two points and click a button to calculate it.
Being able to calculate the slope between two points is something that is absolutely essential to mathematics. It is a concept that is introduced in most schools around the world at the same time pre-algebra or trigonometry is taught and it stays useful even as studies advance past the level of calculus. It’s also a skill that stays useful into more advanced professions, such as in the fields of financial analysis, engineering and economics.
Regardless of why you are using it, you will find that slope can make figuring out the direction between two points much easier.

What Exactly is Slope?
Slope is defined as the ratio of how much something ‘rises’ compared to how much it ‘runs’. In an analysis between two things that are of only two dimensions, this can describe how quickly or slowly something rises or falls.
In more mathematical terms, it describes the change in ‘y’ over ‘x’.

Calculating the Slope Using Our Calculator
The process of using our calculator to obtain the slope of a line is very easy and streamlined.
In order to be able to find the slope between two points, two things are required:
1. One point defined as (x1, y1).
2. Another point defined as (x2, y2).

Once you have all of this data, you can simply follow the steps below in order to promptly receive the slope of your line.
1. Enter your value for ‘x1′ into the x1 field.
2. Enter your value for ‘y1′ into the y1 field.
3. Enter your value for ‘x2′ into the x2 field.
4. Enter your value for ‘y2′ into the ‘y2′ field.

It should be noted that you have to make sure to go from left to right with your coordinates or your slope will be negative. This means that the coordinate pair (x2, y2) should have an x2 value that is smaller than the x1 value in (x1, y1). The reason that you need to be wary of your coordinate pairs being reversed is because slope is calculated from left to right in terms of the domain.
