How are the rise and run between two points on a line related to the line’s slope?
Answer to Problem 3CR
The slope of a line equals to the rise divided by the run.
Explanation of Solution
We know that slope of line is ratio between line’s vertical change and its horizontal change.
We also know vertical change is known as the rise and horizontal change is known as the run.
To find slope of a line we need to divide the rise by the run.
Therefore, the slope of a line equals to the rise divided by the run.
