Explanation:
The quadrilateral will be a parallelogram if the diagonals bisect each other. That will be the case if the sums of their end-point coordinates are the same.
   A + C = (-3, 6) +(9, -9) = (6, -3)
   B + D = (6, 0) +(0, -3) = (6, -3)
Both diagonals have their midpoint at (3, -1.5), so the diagonals are mutual bisectors. The figure ABCD must be a parallelogram.
___
The midpoint of AC is (A+C)/2 = (6, -3)/2 = (3, -1.5).

Answer:
(-3 , 0) (0, 2) (6, -6)
Step-by-step explanation:
Solving for x - intercept: 
2x - 3(0) = -6 
2x = -6 
2x/2 = -6/2
x = -3 
One point would be (-3 , 0) . 
Solving for y-intercept: 
2(0) - 3y = -6
-3y = -6
-3y/-3 = -6/-3
y = 2
Another point would be (0, 2).
When 'x' equals 6:
2(6) - 3y = -6
12 - 3y = -6 
12 - 12 - 3y = -6 - 12
-3y = -18 
-3y/3 = -18/3
y = -6
The third point would be (6, -6).
