Question

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

• A. $3\leftarrow 7\uparrow$
• B. $7\uparrow 4\leftarrow$
• C. $7\uparrow 1\leftarrow$
• D. $4\leftarrow 6\uparrow$

Answer 1

The correct option is B $7\uparrow 4\leftarrow$

The pre-image A is moved 7 units vertically upwards and then 3 units horizontally leftwards to reach the image A.
The transformation involved is called translation.
The translation from A to A' therefore is, \$7\uparrow 4\leftarrow$
