Question

Line segmentAB has vertices A(−3, 4) and B(1, −2). A dilation, centered at the origin, is applied to AB⎯⎯⎯⎯⎯. The image has vertices A′(−1, 43) and B′(13, −23).

A: 1/6
B: 1/3
C: 3
D: 6

Answer 1

B: 1/3

Explanation:

(x,y) = (1/3x,1/3y)

Answer 2

• B: 1/3

Explanation:

It seems the coordinates given are incorrect.

It should read:

• A'(-1, 4/3), B'(1/3, -2/3)

This reflects the rule:

• (x, y) → (1/3x, 1/3y)

Correct choice is B
