1. D)

2. I)

3. A)

4. B)  

5. C)

6. E)

7. F)

8. H)

9. G)

Notes:

1) Know that z=0,x=0,y=0 are perpendicular planes.

2) z = 0 is basically the whole x-y plane.

3) Reduce the equations to see if they become equivalent. For example 6) reduces to one equation, z = 1 so we have only one plane which matches with E). Similarly, you can go from 3 to 2 equations which mean 2 planes.

Cheers!
