Question

Describe the transformation that maps the pre-image A to the image A'.

Answer 1

ANSWER

B) translated 10 units to right and then 10 units down



EXPLANATION

The top vertex of image A has coordinates (-7,7)


The corresponding vertex of A' is (3,-3).


Let the translation vector be


$\binom{x}{y}$


$\binom{ - 7}{7} + \binom{x}{y} = \binom{3}{ - 3}$


This implies that,

$\binom{x}{y} = \binom{3}{ - 3} - \binom{ - 7}{7}$


$\binom{x}{y} = \binom{3 + 7}{ - 3 - 7}$


$\binom{x}{y} = \binom{10}{ - 10}$

Therefore there has been a translation of 10 units to the right and 10 units down.

Answer 2

B. Translated 10 units to the right, and 10 units down
