The coordinates of the point on x-axis which divides the line segment joining the points (2, 3) and (5, -6) in the ratio 1 : 2 are :

1. (2, 0)

2. (-2, 0)

3. (3, 0)

4. (-3, 0)

If the point P(k, 0) divides the line segment joining the points A(2, -2) and B(-7, 4) in the ratio 1 : 2, then the value of k is:

1. -2

2. -1

3. 1

4. 2
