Answer:
The correct option is 2.
Step-by-step explanation:
If a figure rotated 270°counterclockwise with origin as the center of rotation, then
From the given graph it is clear that the coordinates of V are (1,3), the coordinates of V' are
The coordinates of V' are (3,-1).
Therefore the correct option is 2.
