Linear Line:
\n" ); document.write( "(3,6) and (-6,-9)
\n" ); document.write( "m = (y2 - y1)/(x2 - x1)
\n" ); document.write( "m = (6 + 9)/(3 + 6) = 15/9 = 5/3
\n" ); document.write( "y = m(x - x1) + y1
\n" ); document.write( "y = (5/3)(x - 3) + 6
\n" ); document.write( "y = (5/3)x - 5 + 6
\n" ); document.write( "y = (5/3)x + 1
\n" ); document.write( "
\n" );
