Question 195294
<font face="Garamond" size="+2">

Points X, Y, and Z must be collinear, that is they must all be points in the same straight line.  That's because three non-collinear points uniquely define a plane.  If X, Y, and Z were non-collinear, then planes a and b would have to be the same plane in order for each of them to contain the three points.  However, the problem states that the planes are distinct.
