slope m=(11--4)/(4--1)
\n" ); document.write( "m=15/5
\n" ); document.write( "m=3
\n" ); document.write( "-------------------
\n" ); document.write( "y=mx+b
\n" ); document.write( "11=3*4+b
\n" ); document.write( "11=12+b
\n" ); document.write( "b=11-12
\n" ); document.write( "b=-1
\n" ); document.write( "--------------
\n" ); document.write( "y=3x-1
\n" ); document.write( "
