This short video shows the adventure of Slope Dude, which uses the ski run of Slope Dude to demonstrate positive slope, negative slope, a slope of zero, and a slope that is undefined. This is an improvement over a prior video, this one having complete captioning of the narration. For those wanting to recognize the greatness of Slope Dude, you may visit the Etsy store for official Slope Dude products: https://www.etsy.com/shop/DBNoveltiesShop?ref=hp_from_purchased_shops-shop§ion_id=35264195
