a. Using the two data points given above, calculate the linear rate of change (slope) and explain the meaning of this rate of change.(do not make a graph for thisit won't work; you need to calculate the rate of change yourself)

b. Write the linear equation for this function and define your variables (explain what x and y represent in this equation).

c. According to your equation, how many deaths due to cancer will there be in 2016?

d. The population of the US was 291,421,906 in 2000 and 308,745,538 in 2010.Using the number of deaths given above and these population figures, calculate the cancer death rate in number of deaths per 100,000 people for each of the years.
