What Is Slope?
Slope measures the steepness and direction of a line. It's the ratio of vertical change (rise) to horizontal change (run) between any two points on the line.
Formula
m = (y₂ − y₁) / (x₂ − x₁)Example
The slope between points (1, 2) and (4, 8) is (8 − 2)/(4 − 1) = 6/3 = 2.
Frequently Asked Questions
What does a slope of 0 mean?
A slope of 0 means a perfectly horizontal line — no vertical change between points.
What does a negative slope mean?
A negative slope means the line goes downward from left to right.
