In parallelogram ABCD, A = (6, 0), B = (12, -4) and C = (4, -4); then the co-ordinates of vertex D are :

1. (2, 0)

2. (-2, 0)

3. (0, 2)

4. (0, -2)

Given M is the mid-point of AB, find the co-ordinates of:

(i) A; if M = (1, 7) and B = (-5, 10),

(ii) B; if A = (3, -1) and M = (-1, 3).

The point P(2, -7) is reflected in the point (0, 3); the co-ordinates of the image of point P are :

1. (2, 13)

2. (2, -13)

3. (-2, -13)

4. (-2, 13)

Points A and B have co-ordinates (3, 5) and (x, y) respectively. The mid-point of AB is (2, 3). Find the values of x and y.
