The slope of a line is the steepness of a line or a curve, some other names for the slope are “gradient, slant, and incline.” To calculate the slope, we use the following formula. General formula of the slope: Generally, we use the following formula to calculate the slope “m”. m = rise / run = (y2 – y1) / (x2 – x1)  1. “x1, x2, y1, and y2 are the points on which the line lies on the cartesian coordinate. 2. “m” is the slope. Topographies: This slope calculator has many features that make it unique compared to other calculators. Input field: The input fields are very easy to use and very flexible. Separate boxes are designed for the ease of the user. Erasing all input: The “reset” button allows you to erase all the input at once.
