A'b has endpoints located at a' (0, 0) and b' (2, 0). it was dilated at a scale factor of 1/2 - from center (2, 0). which statement describes the pre-image?
ab is located at a (-2, 0) and b (2, 0) and is half the length of a'b'.
ab is located at a (-2, 0) and b (2, 0) and is twice the length of a'b.
ab is located at a (-1,0) and b (1,0) and is half the length of a'b.
ab is located at a (-1,0) and b (1.0) and is twice the length of a'b.

Second option.

Step-by-step explanation:

A dilation is defined as a transformation in which the image has is the same shape as the pre-image, but has a different size.

We know that the endpoints of A'B' are:

Observe the first figure attached. You can see thatt A'B' has a lenght of 2 units.

 Since we know that the center of dilation is at  and we also know that A'B' is obtained by dilating AB by a scale factor of , we can say that:

As you can observe in the second figure attached, since the lenght of AB is 4 units, the coordinates of the the points A and B are:
