In 1995, the life expectancy of males in a certain country was 66.9 years. In 2002, it was 69.7 years. Let E represent the life expectancy in year t and let t represent the number of years since 1995.
\n" ); document.write( "Find a linear function E(t) that fits the data.
\n" ); document.write( "---------------------------------\r
\n" ); document.write( "\n" ); document.write( "You have two points: (0,66.9) and (7,69.7)
\n" ); document.write( "slope = (69.7-66.9)/7 = 2/5
\n" ); document.write( "---------------------------
\n" ); document.write( "Form E = mt+b
\n" ); document.write( "You have y,x,and m; solve for \"b\":
\n" ); document.write( "66.9 = (2/5)(0)+b
\n" ); document.write( "b = 66.9
\n" ); document.write( "EQUATION:
\n" ); document.write( "E(t) = (2/5)t +66.9
