How slope is calculated

The slope of a line through two points (x₁, y₁) and (x₂, y₂) is m = (y₂ − y₁) / (x₂ − x₁) — rise over run. This tool also computes the angle of inclination (arctan of the slope, in degrees), the Euclidean distance between the points (√((Δx)² + (Δy)²)), the midpoint, and the full slope-intercept equation y = mx + b where b = y₁ − mx₁. A vertical line has an undefined slope; a horizontal line has slope 0. All values round to 4 significant figures.
