The coordinates of parallelogram UVWZ are U(a, 0), W(c-a, b), and Z(c,0). Find the coordinates of V without using any new variables

A• (0, b)
B• (c, b)
C• (a, b)
D• (b, 0)

won’t let me ask a question unless I answer one but I honestly don’t know and why do I pay for this if I can’t even ask questions

Choice A.

(0, b)

==================================================

Explanation:

Pick any random 3 numbers you want for a,b,c.

- a = 1
- b = 2
- c = 3

The points U, W and Z become

- U = (a,0) = (1,0)
- W = (c-a, b) = (3-1, 2) = (2,2)
- Z = (c, 0) = (3, 0)

Or in short,

- U = (1,0)
- W = (2,2)
- Z = (3, 0)

Plot each of those points on the same xy grid.

Next, using a different color, plot each of the answer choices.

- A is at (0,b) = (0, 2)
- B is at (c,b) = (3,2)
- C is at (a,b) = (1,2)
- D is at (b,0) = (2,0)

You should find that point A helps form a parallelogram, while the other answer choices don't lead to a parallelogram.

See the screenshot below. I used GeoGebra to make the diagram. Desmos is another useful tool as well.
