BRAINLIESTTT ASAP! PLEASE HELP ME :)

============================================================

See the diagram below. I have marked 5 faces of the rectangular prism.

Face BAF or plane BAF is the left face or the left wall of the rectangular prism. It is marked in green for each drawing. We only need 3 points to uniquely identify a plane. So we don't need to say "Face BAFG" as that fourth point is unnecessary.

The blue faces are the ones attached to the green face. They intersect the green face and share common edges. For instance, face BAF and face BCD intersect at segment BA. Points B and A, and everything in between are found in both planes BAF and BCD.

So we have

all shown in blue in the diagram below, and all of those blue faces attach or intersect the green face at some segment.

answer: i think it is (1,-2)
