  NOT a parallelogram

Step-by-step explanation:

Segment QT is not parallel to vertical line segment RS, so QRST cannot be a parallelogram.

_____

A parallelogram has diagonals that have the same midpoint. That means the coordinates of opposite vertices sum to the same value. Here, we have ...

  Q+S = (-10+1, -2-7) = (-9, -9) ≠ R+T = (1-11, -1-8) = (-10, -9)

Since the diagonals do not have the same midpoint, the figure cannot be a parallelogram.
