Answer 2

see how they all sit on plane Z, the flat plane? So you can call plane Z as "plane XTV"

Answer 3

Point S is outside the plane and so you can cross out any answer choice that has "S" in it. You can also cross out answer choice that has "Z" in it because "Z" is not a point on the plane but it represents the plane. You need three points ON the plane to represent the plane.
