The age-adjusted death rate from heart disease was 412.1 per 100,000 population in 1980 and 232.3 in 2003.
(a) Assuming that the death rate declined linearly, find an equation of the form y = mx + b that gives the number y of deaths per 100,000 in year x, with x = 0 corresponding to 1980. Round m to two decimal places.
(b) Use the equation in part (a) to estimate the death rate in 2001.
(c) Assuming that the equation remains accurate, estimate the death rate in 2009.
(d) Is the equation likely to remain accurate over the next three decades? Give reasons for your answer.
