You can put this solution on YOUR website!
For any two points on a line:
\n" ); document.write( "(x1,y1)
\n" ); document.write( "and
\n" ); document.write( "(x2,y2)
\n" ); document.write( ".
\n" ); document.write( "The slope (m) can be found by:
\n" ); document.write( "m = (y2 - y1)/(x2 - x1)
\n" ); document.write( ".
\n" ); document.write( "You were given two points:
\n" ); document.write( "(x1,y1):(4,1)
\n" ); document.write( "(x2,y2):(8,-5)
\n" ); document.write( ".
\n" ); document.write( "Plugging it in:
\n" ); document.write( "m = (y2 - y1)/(x2 - x1)
\n" ); document.write( "m = (-5 - 1)/(8 - 4)
\n" ); document.write( "m = (-6)/(4)
\n" ); document.write( "m = -3/2 (slope) \n" ); document.write( "

\n" );
