The slope formula you would use in the problem is:\r
\n" ); document.write( "\n" ); document.write( "Y2 - Y1/X2 - X1\r
\n" ); document.write( "\n" ); document.write( "so using the cordinates given\r
\n" ); document.write( "\n" ); document.write( "-10 - 3/10 - 1\r
\n" ); document.write( "\n" ); document.write( "-13/9\r
\n" ); document.write( "\n" ); document.write( "so the slope (m) = -13/9\r
\n" ); document.write( "\n" ); document.write( "this is called the Point-Slope equation
\n" ); document.write( "
\n" );
