You can put this solution on YOUR website!
slope is change of y over the change in x\r
\n" ); document.write( "\n" ); document.write( "(2.31-1.26)/(2006-1997)
\n" ); document.write( "1997=x=1
\n" ); document.write( "2005=x=9
\n" ); document.write( "x=4=2005-5
\n" ); document.write( "x=9+13 =2018
\n" ); document.write( "
