Answer: The answer is A .
Explanation:
Let's write down the coordinates on the graph then use it to answer the question.
A ( -2,1) B (2,1) C (2,-1) D (-2,-1) and is being dilated by a scale factor of 3 so u will multiply each value by three to find the new vertices.
A( -2 *3, 1*3) = A (-6,3)
B (2*3, 1*3) = B ( 6,3)
C ( 2*3, -1*3) = B (6,-3)
D ( -2 *3,-1*3) = D (-6, -3)
