You have been invited to present statistical information at a conference. To prepare, you must perform the following tasks:
Disease 1985 1990 1995 2002
Heart Disease 771169 720058 737563 696,947
Cancer 461563 505322 538445 557,271
Plot this data for each disease as points in a rectangular coordinate system.
Using a smooth line, connect your data points for each disease.
On a separate graph, plot only the years 1985 and 2002 and connect the points with a straight line.
Calculate the slope of each line.
Write the equation of each line in the slope-intercept form.
Using the equations of each line, make a reasonable prediction as to the number of deaths we might expect in 2005 due to each of these medical conditions.
Please include a response to this two part follow-up question with your submission.
Can the graphs that you constructed be classified as functions? Explain.
What would the real-world implications be if these numbers were actually part of the domain and/or range?
