**slope calculator** solves the line slope equation either when 2 points are given or when 1 point and the slope are known. You can read more on this topic below the tool.

## How does this slope calculator work?

First of all it offers two methods to solve the slope line equation as detailed here:

- 1
^{st}approach is the one that requires both coordinates of the two points to be given. - 2
^{nd}method is the one that takes account of at least the coordinates of one point plus either the slope or the angle in incline.

The algorithm of this *slope calculator* is based on these formulas:

- Slope (M) = (y2-y1)/(x2-x1)

- Distance (C) = Square Root of ((x2-x1)2 + (y2-y1)2 )

- Line of Equation: y = Mx + b

- Angle in degrees = arctan(M)

- Angle in radians = Angle in degrees * 0.0174532925
