疑问出自这句话
The line a t + by + c = 0 in 2-space is dual
to the point (a, b, c) E P2 in projective 2-space.
The dual point must live in projective space, since the dual
(a, b, c) must be equivalent to the dual (ka, kb, kc), as the
line at + by + c = 0 is equivalent to the line kat + kby +
kc = 0, k # 0.
