Answer:
C. (-7, 4)
Step-by-step explanation:
Diagonals of a parallelogram share a common midpoint
Let the fourth vertex be (x,y)
(-2-4)/2 , (4+0)/2 = (x+1)/2 , (y+0)/2
-3 , 2 = (x+1)/2 , y/2
-3 = (x+1)/2
x + 1 = -6
x = -7
y/2 = 2
y = 4
w=9x+4
2(3x-3+w)=12x+2
6x-6+2w=12x+2
subtract 6x for both sides
-6+2w=18x+2
add 6 for both sides
2w=18x+8
Divide by 2 to find w
-28*F, hope this helps!
A is incorrect
when you see -(- it makes the thing plus sign/positive
