4) I decide to walk home from school. School is 5 miles from home and I walk at an average rate of 4
miles per hour. This linear equation models this: M ( h)  5  4h , where M is my distance in miles from
home and h is the number of hours I’ve walked.
a) What does M (0) equal and what does it mean in the context of this story?
