(1 point) The distance between a point P and a plane: a(x - X) + b(y - yo) + c(Z - Zo ) = 0 can be given by: PR . n d = In| Where n = (a, b, c) and R is any point on the plane (in particular it can be (x0, yo, Zo) ). Find the distances between the plane x - 3y + z = -5 and points: 1. (0, 0, 5) : 2. (-2, -1, 2) : 3. (3, 1, 3)
