Given that the symmetric point P2 (3-2a, 2a-5) of P1 about X axis is the integral point in the third quadrant (the point whose abscissa and ordinate are integers is called integral point), then the coordinate of P1 is______ ．

Given that the symmetric point P2 (3-2a, 2a-5) of P1 about X axis is the integral point in the third quadrant (the point whose abscissa and ordinate are integers is called integral point), then the coordinate of P1 is______ ．

Given that P2 (3-2a, 2a-5) is the integral point in the third quadrant, then there is 3 − 2A ＜ 02A − 5 ＜ 0, and the solution is 1.5 ＜ a ＜ 2.5. Because a must be an integer, so a = 2, substituting it, we can get the coordinates of P1 (- 1, 1)
