**Crime Statistics** The murder rate in large cities (over 1 million residents) can be related to that in smaller cities (500,000–1,000,000 residents) by the following linear model:

*y* is the murder rate (in murders per 100,000 residents each year) in large cities and *x* is the murder rate in smaller cities. During the period 1991–1998 the murder rate in small cities was decreasing at an average rate of 2 murders per 100,000 residents each year. Use the chain rule to estimate how fast the murder rate was changing in larger cities during that period. (Show how you used the chain rule in your answer.)
