P is the mid-point of AB and Q is the mid-point of AP. If the coordinates of A are (2, -4) and coordinates of Q are (1, -1), then the coordinates of B are:

1. (1, -1)

2. (-1, 6)

3. (-2, 6)

4. (-2, 8)

The line 2x + y - 4 = 0 divides the line segment joining A(2, -2) and B(3, 7) in the ratio:

1. 2 : 3

2. 2 : 5

3. 2 : 7

4. 2 : 9
