Is image to answer the question a one, - 3 b 2, - 4 a - 4, - 12 be - 8, - 16 determine the scale factor used in the dilation of the line segment AB centered at the origin is it 2 1 4 4 - 4
The scale factor used in the dilation of the line segment AB can be determined by calculating the ratio of the lengths of the dilated segment to the original segment.
In this case, the lengths of the segments are as follows:
Original segment AB: |-3 - 2| = 5 units
Dilated segment AB: |-12 - 8| = 20 units
So, the scale factor used in the dilation of the line segment AB is 20/5 = 4.
Therefore, the correct answer is 4.
