( 1)P(x,y)→P'(x,y+ 1); Translate one unit upwards.
(2)P(x,y)→P'(x- 1,y); Translate one unit to the left.
(3)P(x,y)→P'(x+2,y+3); Translate two units to the right and three units up.
(4)P(x,y)→P'(x-2,y- 1)。 Pan two units to the left and one unit down.
2. Move point P(m+2, 2m+4) to the right by 1 unit length to point P', and the coordinates of point P' are (m+3, 2m+4).
3. After the point P( 1, -m) is shifted to the right by 2 unit lengths, it is shifted upward by 1 unit length to get the point Q(n, 3), and the coordinate of the point K(m, n) is (-2, 3).
