Question

Ab has endpoints at (-9, 12) and (3, -6). Its transformation a'b' has endpoints at (-3, 4) and (1, -2). What type of transformation occurred? Are lengths of segments affected by this type of transformation? Justify. A) reflection; no; the lengths of the two segments are the same. b) rotation; yes; the length of segment a'b' is longer than the original segment ab. c) dilation by a scale factor of 3; yes; the length of segment a'b' is shorter than the original segment ab. d) dilation by a scale factor of 1 3 ; yes; the length of segment a'b' is shorter than the original segment ab.

Answer 1

A: (-9, 12) → (-3, 4) both x and y are divided by 3

B: (3, -6) → (1, -2) both x and y are divided by 3

Therefore, this is a dilation of
`(1)/(3)`

Answer: D
