Just average the two x-values and then average the two y-values.
The two x-values are -1 and 2. Add them together and divide by 2 so -1 + 2 = 1 and dividing by 2 gives 1/2.
The two y-values are -5 and 0. Add them together and divide by 2 so -5 + 0 = -5 and dividing by 2 gives -5/2.
So the midpoint is (1/2, -5/2)
