Question

Let A, B, C, D be distinct points in 3-space with position vectors abc, d respectively. Let E be the midpoint of the line segment AC.

Let M be the plane passing through the three points A,B,C and let N be the plane passing through the three points A,C,D. Assume that the points are chosen so that M and N are distinct, well-defined planes.

i) which is r=d+λ(bd) out of the list attatched 

ii) which is (a+b+c)/3 out of the list attatched 

is the distance from the point E to the plane N
is a vector equation for the line where M and N intersect
is the distance from the point B to the point E
is a real number less than 0
is the position vector of a point that lies on N but not on M
is the equation of the plane M
is a vector equation for a line that is contained in M but not in N
is the position vector of a point that lies on M but not on N
is the position vector for the midpoint of the line segment AE
is the position vector of a point that lies neither on N nor on M
is a vector equation for a line that intersects M at exactly one point
is a meaningless expression
