ANSWER
T' = (-9, -3)
U' = (-1, 0)
V' = (-9, 3)
W' = (-10, 0)
EXPLANATION
When you go vertically units tup the xycoordinate of each of the vertices is increased by 6.
That is:
T = (-9, -9) to T' = (-9, -9+6) = T' = (-9, -3)
U = (-1, -6) to U' = (-1, -6+6) = U' = (-1, 0)
V = (-9, -3) to V' = (-9, -3+6) = V' = (-9, 3)
W = (-10, -6) to W' = (-10, -6+6) = W' = (-10, 0).
Hence, the coordinates of the vertices after a translation 6 units up are:
T' = (-9, -3)
U' = (-1, 0)
V' = (-9, 3)
W' = (-10, 0)
