A factory has a conveyorâ belt, Conveyorâ 1, which brings the supplies into the factory. The conveyor belt rises 8 ft for every 4 ft it runs. The factory has another conveyorâ belt, Conveyorâ 2, which sends the products out of the factory. This conveyor belt descends 21 ft for every 7 ft it runs. Find the slope of each conveyor belt. Which conveyor belt isâ steeper?
