I just ate a lot of food and i'm about to fall into a food coma, I just need the answers. Luis is at a friend’s house that is several miles from his home. He starts walking at a constant rate in a straight line towards his home. The expression -4t + 16 gives the distance in miles that Luis is from his home after t hours. Answer the following questions:
▪ How many miles away from his home did Luis start?
▪ How fast is Luis traveling away from his friend’s house?
▪ Why is the rate negative?
▪ How far way from his house is Luis after 3 hours?
