In the plane rectangular coordinate system, O is the origin, the straight line L: X = 1, the points A (2 2,0), E, F and M are all on the straight line L, the points E and F are symmetrical about the point M, and the straight line EA and the straight line OF intersect at the point P. 。
(i) If the coordinate of point m is (1,-1),
(1) When the coordinates of point F are (1, 1), as shown in the figure, find the coordinates of point P;
② When point F is a moving point on a straight line L, remember point P (x, y) and find the resolution function of y about x. 。
(2) If point M( 1, m) and point F( 1, t), where t≠0 and point P are PQ⊥l at point Q, when OQ=PQ, try to express m with a formula containing T. 。
