Question

How is the pre-image(A) related to the image(A')?

• A. $3\uparrow 5\leftarrow$
• B. $3\leftarrow 1\uparrow$
• C. $6\leftarrow 1\uparrow$
• D. $6\leftarrow 3\uparrow$

Answer 1

The correct option is D $6\leftarrow 3\uparrow$

The pre-image A is moved 6 units horizontally leftwards and then 3 units vertically upwards to reach the image A.
The transformation involved is called translation.
The translation from A to A' therefore is, $6\leftarrow 3\uparrow .$
