So the answer is D

In this geometric transformation, when we dilate about the origin. We can calculate the dilated figure by simply multiplying each coordinate by its scale factor. But only if it's done, the dilation about the origin.

Since our pre-image is:

1(-2,0), X(-1,3), 7(2, -1), (2,-3)

The Dilated figure is

1'(-3,0) X'(-1,5,4.5) 7'(3,-1.5), (3,-4.5)

Notice the names of the points on the options, are changed, but the standard is to call the new image points with an apostrophe above.

So the answer is D
