Run

Definition

Run is the horizontal change between two points on a graph. It is used in conjunction with rise to calculate the slope of a line.

5 Must Know Facts For Your Next Test

1. The run is calculated as the difference in the x-coordinates of two points (x2 - x1).
2. Run is always measured horizontally, regardless of the direction of the line.
3. Together with rise, run determines the steepness or slope of a line.
4. A positive run indicates movement to the right along the x-axis, while a negative run indicates movement to the left.
5. In slope-intercept form (y = mx + b), 'm' represents the slope and can be found using both rise and run.
