Answer:
2
Step-by-step explanation:
A parallelogram is 4 sided figure. Since it is a irregular, the sides and angles must be in different measures.
When we rotating the irregular parallelograms about the midpoint of its diagonal, it will coincide with its pre-image at 180 degrees and 360 degrees.
Therefore, the answer is 2.
1/3

-2
given 2 points on a line (x1, yx) and (x2,y2)
the formula for slope, m = (y2-y1) / (x2-x1)
in this case,
x1 = 4, y1 = 3, x2 = 2, y2 = 7
Hence,
m = (7-3) / (2-4) = 4 / -2 = -2
