not sure what you mean by the midpoint formula, but another way to do it is to calculate the slopes of the lines joining the points and seeing that they are parallel:
Line from (+3, +8) thru (-1, +9): Y = -1/4X +35/4 = -.25X +8.75
Line from (+6, +2) thru (+3, +8): Y = -2X +14
Line from (+2, +3) thru (+6, +2): Y = -1/4X +7/2 = -.25X +3.5
Line from (-1, +9) thru (+2, +3): Y = -2X +7
as you can see the opposite sides have slope of -2 and -1/4 so it is a parallelogram.
