In 1991, the life expectancy of males in a certain country was 66.1 years. In 1998, it was 68.5 years. Let E represent the life expectancy in year t and let t represent the number of years since 1991.
\n" ); document.write( "---
\n" ); document.write( "2 points: (0,66.1), (7,68.5)
\n" ); document.write( "---
\n" ); document.write( "slope = (68.5-66.1)/7 = 12/35
\n" ); document.write( "int: 66.1
\n" ); document.write( "------------------------------------
\n" ); document.write( "the linear function E (t) that fits the date is:
\n" ); document.write( "E (t) = (12/35)t +66.1
\n" ); document.write( "(round to the nearest tenth)
\n" ); document.write( "----------------------------------------------
\n" ); document.write( "Use the function to predict the life expectanc of males in 2008.
\n" ); document.write( "E (17) = (12/35)17+66.1 = 71.93
\n" ); document.write( "(round to the nearest tenth)
\n" ); document.write( "===================================
