A line passing through the point A(9, 0) makes angle of 30° with the positive direction of x-axis. If this line is rotated about A through an angle of 15° in the clockwise direction, then its equation in the new position is :

1. 2 3 y − + x = 9
2. 2 3 y − + y = 9
3. 2 3 y + + x = 9
4. 2 3 y + + y = 9

Correct answer: 2 3 y − + x = 9
