Find the image vertices for a dilation with center (0 0) and a scale factor of 4
(-3,1)x4=-12,4
(-1,4)x4=5,6
(2,3)x4=9,2
(4,-3)x4=4
wait if your so against cheating then why are you here I-
(-3,1)x4 = -12,4
(-1,4)x4 = -4,16
(2,3)x4 = 8,12
(4,-3)x4 = 16,-12
Not sure how you cam up with those other bizarre answers
