Question

Use the diagram.

Answer 1

4: line S could also be called UX (points that lie on the line)

5: Q,T,P (these points all lie in plane K)

6: T,R,Y (these points all lie in line TY)

7: Q,T,P (other than given name K, you can name a plane using 3 coplanar points. we use the same answer as 5 because that question already asked us to find 3 coplanar points)
