Rory is staying in a cabin on a hill 300 feet above sea level. she walks down the hill to the water’s edge. the equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. which values are viable points, and what are their values in the table relating t and e? a = b = c =
