I can understand why it might be tough, so I'm here to help.
Translation is as simple as moving the points as told.
For example, do you see where point T currently resides? From there you'd move it 4 units to the left and 5 down, where it'd end up at (-4,-3). Now do the same for every point.
Point T would end up at (-4,-3)
Point S would end up at (-2,-2)
Point R would end up at (0,-3)
