what are the new vertices of quadrilateral DEFG, if the quadrilateral is translated downward one unit?

ANSWER
• D'(-5, 0)
,• E'(-3,4)
,• F'(5,0)
,• G'(3,-4)
EXPLANATION
When the quadrilateral is translated 1 unit down, only the y-coordinates change,
Hence, the new vertices of the translated quadrilateral are:
• D'(-5, 0)
,• E'(-3,4)
,• F'(5,0)
,• G'(3,-4)
