I believe it is D. The lowest number on the y-axis is -4, and the highest is 0. -4<=y<=0
Blue= 4
Orange=2
Hope this helped you! :)

If ~v = hv1, v2, v3i and ~w = hw1, w2, w3i are vectors and c is a scalar, then
(a) c~v = hcv1, cv2, cv3i
(b) ~v + ~w = hv1 + w1, v2 + w2, v3 + w3i
(c) ~v − ~w = hv1 − w1, v2 − w2, v3 − w3i.
C) 3:1
For every 3 people who prefer band A toothpaste 1 person preferred band B toothpaste:
3 to 1=3:1.
