What is Slope?
Slope measures the steepness and direction of a line. It’s calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on a line.
slope (m) = rise / run = (y₂ – y₁) / (x₂ – x₁)
Slope is a fundamental concept in algebra, calculus, and geometry, with applications in physics, engineering, economics, and computer graphics.
