On most mountain roads the grade or slope of the road is measured in a percentage. Percentage is out of 100 so if the road grade was 8% the road would drop or rise 8 feet for every 100 feet of travel. 100 feet is the run and the % grade is the the rise. Therefore road grades can be graphed on a coordinate plane.
