The scatter plot shows the distance a car drives and the time it takes to get to the
destination for many trips.

A line that models the data is given by the equation y = 0.93z + 4.15,
where y represents the travel time in minutes, and x represents the distance travel in
miles.
1. The slope of the line is 0.93. What does this mean in this situation? Is it
realistic?
2. The y-intercept is (0, 4.15). What does this mean in this situation? Is it
realistic?
