You can put this solution on YOUR website!
slope= (b - a)/(a - b)= - 1, les asume that b=4 and a=7, then (4 - 7)/(7 - 4) =
\n" ); document.write( "- 3/3= -1\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "slope = (b -(-a))/ (a -(-b)) (b + a )/( a + b) = 1\r
\n" ); document.write( "\n" ); document.write( "les asume that b=4 and a=7,
\n" ); document.write( "(4 + 7)/(7 + 4) = 1
\n" ); document.write( "
\n" );
