The answer is (-2, -6)
to rotate 90 degrees counterclockwise, you do (-y, x)
Answer:
6
Step-by-step explanation:
because you divided the amount of mile by the amount of time it took to get your answer
From this picture you can calculate coordinates of triangles' vertices:

.
Since
you can conclude that points A, B, C are rotated by

about the point (-0.5,0) to form points J, G, H, respectively.
Answer: A is correct choice.
