Slope calculator

Find the slope between two points, slope from equation, slope-intercept form, point-slope form, and parallel/perpendicular slopes.

(x₁,y₁)(x₂,y₂)

How to find slope

Slope = rise/run = (y₂−y₁)/(x₂−x₁). In slope-intercept form y = mx + b, m is the slope. Parallel lines have equal slopes; perpendicular lines have slopes that multiply to −1.
