8 Best Free Online Slope Calculator Websites

Here is a list of the best free online slope calculator websites. The slope is the amount of slant a straight line has. In mathematics, it is also known as the gradient. A slope calculator determines the slope of the line from the coordinates of the two known points.

This post covers 8 websites where you can calculate the slope of a straight line for free. These calculators take the coordinates and find the slope. Along with the slope, you also get the angle of the slope and the distance between the points. The results include a graph of the line with additional calculations such as percentage grade, Point Slope Form, Slope Intercept Form, Slope-intercept form of the line, and more. Some calculators can also find the slope when only one point is known along with the distance.

My Favorite Online Slope Calculator Website

OmniCalculator.com is my favorite slope calculator website on this list. It has a neat and clean interface where you insert the coordinates of the point and get the slope. It can also calculate the slope from the slope angle. You can use this calculator in reverse as well when only one point is known. Apart from just calculation, it nicely explains the slope with a graph and examples.

You can also check out our lists of the best free Online Nernst Equation Calculator Websites, Websites with Permutation Calculator Online, and Online Binomial Distribution Calculator Websites.
