Question

Points A(-2, 4), B(1, 3), C(4, -1) and D form a parallelogram. What are the coordinates of D?

Answer 1

A. (5,5)
B. (0,0)
C. (1,-2)
D. (1,0)
E. (3,4)

Answer 2

Let me explain to you why the answer is (1,0)

Answer 3

As a vector
A-B =D-C
(-3,1) =(-4+x, 1+y)
Hence
-4+x =-3
y+1= 1

Answer 4

So y=0 and x=1

Answer 5

Thank you so much, I actually did what the other person's diagram said, but regardless thank you so much :)
