There are something look like bugs.

When I use the model to solve a math problem, I found it will fall in to think if vector PA is from P to A, or from A to P.
There is the original problem:
**问题**
已知点 $ A(-1, 0) $ 和 $ B(2, 1) $，移动点 $ P(x, y) $ 满足 $ PA \perp PB $。
(1) 找出点 $ P $ 轨迹的方程；
(2) 确定这个轨道的形状并解释原因。
