Question

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

Answer 1

Yes! It was correct, option D

Explanation:

D. (1, 0)

Answer 2

Take A and B points and
Let m be the difference of x-coordinates and n, that of y-ones.

`m=|-2-1|=3\;\;\;\;\;n=|4-3|=1`

With this, we know D is 3 units to the left from C and 1 unit above C, that is:

`D=(4-m,\;-1+n)=(4-3,\;-1+1)=(1,\;0)`
