Yes, just represent your points with position vectors. Sage can add vectors to vectors and apply linear transformations to vectors.

For example:

sage: v = vector([1,2,3])
sage: M = matrix([[1,0,0],[0,2,0],[0,1,1]])
sage: M
[1 0 0]
[0 2 0]
[0 1 1]
sage: pt = vector([0,1,0])
sage: v + M*pt  # apply affine linear transformation to point `pt`
