slope = m = dy/dx
\n" ); document.write( "m = (1265 - 1137)/(2012 - 2004)
\n" ); document.write( "m = 16
\n" ); document.write( "---
\n" ); document.write( "linear equation for the years 2004 to 2012:
\n" ); document.write( "n = 16t + 1137
\n" ); document.write( "---
\n" ); document.write( "n for the year 2000:
\n" ); document.write( "n = 16t + 1137
\n" ); document.write( "n = 16*(2000-2004) + 1137
\n" ); document.write( "n = 16*(-4) + 1137
\n" ); document.write( "n = 1073
