Slope

Algebra 1 · Linear Functions

Definition

Slope is the steepness of a line, found as rise over run, or the change in y over the change in x.

Examples

  • From (0,1) to (2,5), slope = 4/2 = 2.
  • A horizontal line has slope 0.

Key rule

slope = rise/run = (y2 − y1)/(x2 − x1).

Memory hook

Slope = rise over run.
