What is the best name for the figure with the following coordinates? (4, 1), (1, 1), (3, –2), and (0, –2)

The points form two horizontal sides: (4, 1) to (1, 1), and (3, −2) to (0, −2). The other sides have matching slope 3: from (4, 1) to (3, −2), and from (1, 1) to (0, −2). Since both pairs of opposite sides are parallel, the figure is a parallelogram. It is not a rectangle because the horizontal sides meet the slanted sides at angles that are not right angles.
