Question

What relationship is used to find the slope of a line?

Answer 1

`m = (y2 - y1)/(x2 - x1)`

Explanation:

slope formula

Answer 2

`(rise)/(run)`

Explanation:

The slope of a line is calculated by dividing the rise by the run.

In the attached example, the rise is 1 and the run is 2, so the slope is 1/2. The rise is the distance the line goes up. The run is the distance the line goes to the right for each (rise) units. The line below goes up 1 and right 2 over and over again.
