WebANSWER: If A defines a linear transformation via T (x) = A x, then T must satisfy T (0) = 0 by the definition of a linear transformation (choose c = 0 in the definition). Since the desired transformation we want does not satisfy this, no linear transformation can achieve the translation desired.
