Four coordinates lying on the 3rd quadrant of the Cartesian plane are as follows:
C' = (–6, –5)
D' = (–6, –3)
E' = (–4, –3)
F' = (–4, –5)
<u>Translation</u>:
Since you've been asked to translate the coordinates of the vertices 2 units right and 8 units up, you'll need to add 2 to its x-coordinate and 8 to its y-coordinate.
