2) Suppose you have determined a base u for the plane x+2y+z=0 (The plane is therefore a plane in R3) Which of the following applies? A: The base u is a base for R3 B: Adding exactly one vector to the base u gives a base for R3 C: Adding all the vectors in the default base u to the base gives a base for R3 D: Adding exactly two vectors to the base u gives a base for R3.
