Do it like this one.
\n" ); document.write( "=================
\n" ); document.write( "(2, -8) and (x, 2); slope: -10/3
\n" ); document.write( "----
\n" ); document.write( "Slope m = diffy/diffx
\n" ); document.write( "m = (-8-2)/(2 - x) = -10/3
\n" ); document.write( "-10/(2-x) = -10/3
\n" ); document.write( "-30 = -10(2-x) = -20 + 10x
\n" ); document.write( "10x = -10
\n" ); document.write( "x = -1
\n" ); document.write( " \n" ); document.write( "
