Let X equal the number of years since 1992, and let Y equal the number of participants. \r
\n" ); document.write( "\n" ); document.write( "Year Male Female
\n" ); document.write( "1992 7.18 3.44
\n" ); document.write( "1997 8.30 5.35
\n" ); document.write( "--------------
\n" ); document.write( "Male DATA:
\n" ); document.write( "You have two points: (0,7.18) and (5,8.30)
\n" ); document.write( "slope = [8.3-7.18]/[5-0] = 1.12/5 = 0.224
\n" ); document.write( "Y-intercept = 7.18
\n" ); document.write( "EQUATION: y= 0.224x+7.18
\n" ); document.write( "---------------
\n" ); document.write( "Female DATA;
\n" ); document.write( "You have two points: (0,3.44) and (5,5.35)
\n" ); document.write( "Find the slope, the y-intercept, and write the equation.
