The slope of a line is given by:
\n" ); document.write( " $\"m+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"$
\n" ); document.write( "In your problem, (2, 4) are ( $\"x%5B1%5D\"$ , $\"y%5B1%5D\"$ ) and (4, -2) are ( $\"x%5B2%5D\"$ , $\"y%5B2%5D\"$ )
\n" ); document.write( "Make the appropriate substitutions to get:
\n" ); document.write( " $\"m+=+%28-2-4%29%2F%284-2%29\"$ Simplify.
\n" ); document.write( " $\"m+=+-6%2F2\"$
\n" ); document.write( " $\"m+=+-3\"$ This is the slope. \n" ); document.write( "

\n" );
