It is 8x<span>√<span>2<span>x i hope this helps if not my bad.</span></span></span>
There are 3 more dots above the 13 than are above the 12, so the appropriate choice is ...
... A. 3
(0,0)-->(0,0)
(3,-1)-->(9,-3)
(3,3)-->(9,9)
so what you will plug after the dilation will be the points on the right/
hope i help
