A point P(-7, 8) is first reflected in the origin and then in x-axis to get the point Q. The co-ordinates of point Q are :

1. (-7, 8)

2. (7, 8)

3. (7, -8)

4. (-7, -8)

A point P is reflected first in the y-axis and then in the origin to get the point (6, 6). The co-ordinates of the point P are :

1. (6, -6)

2. (-6, -6)

3. (-6, 6)

4. (6, 6)

The point P(4, -8) is reflected in the line x = 0 to get the point R. The co-ordinates of point R are :

1. (4, -8)

2. (-4, 8)

3. (4, 8)

4. (-4, -8)

The point P(5, 5) is first reflected in line y = 0 and then in x-axis to get the point Q. The co-ordinates of point Q are :

1. (5, 5)

2. (-5, 5)

3. (5, -5)

4. (-5, -5)
