In the year 1980, there were 12 thousand female inmates in federal and state prisons. By 2009, the number increased to 128 thousand. Let x represent the year, and let y represent the number of prisoners (in thousands).
a. Using the ordered paired (1980,12) and (2009,128)find the slope of the line.
=(128-12)/(2009-1980).
=116/29.
=4.
b. Interpret the slope in the context of this problem.
Slope reresents number of thousand female inmates per year.
It means there are 4 thoousand female inmates in ayear.
