A translation of each point (x, y) of a figure can be described using the coordinate notation (x, y) -> (x + a, y + b), where a represents the horizontal distance moved and b represents the vertical distance moved. For triangle PQR with vertices P(-3, -1), Q(0, -1), and R(-1, -3), find the coordinates of the vertices of the image after the translation (x, y) -> (x - 5, y + 7).
