Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a lines steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that m describes based on its sign and value:

• A line is increasing, and goes upwards from left to right when m larger than 0
• A line is decreasing, and goes downwards from left to right when m smaller than 0
• A line has a constant slope, and is horizontal when m = 0
• A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator.

The slope is represented mathematically as:
m = (y2 - y1) / (x2 - x1)

Refer to the Pythagorean theorem we can calculate the distance provided in the calculator:
d = √((x2 - x1)² + (y2 - y1)²)

Given the slope (m), it is possible to find angle ° using the following equation:
Angle ° = tan⁻¹(m)
