Parallelogram FGHI on the coordinate plane below represents the drawing of a horse trail through a local park. In order to build a scale model of the trail, the drawing is enlarged on the coordinate plane. If two corners of the trail are at point A (0, 4) and point D (-6, -5), what is another point that could represent a corner of the trail?

    ok... first we have a model and we have to sketch the new one, with new coordinates. Now first thing to do is we need to know how much bigger will it be... so we need to find distance between IF and DA and we have: \[\LARGE d=\sqrt{(-6+8)^2+(6-3)^2}\] \[\LARGE d=\sqrt{4+9}\] \[\LARGE d=\sqrt{13}\] so distance between points IF is \(\sqrt{13}\) now let's find distance between points DA \[\LARGE d=\sqrt{(0+6)^2+(4+5)^2}\] \[\LARGE d=\sqrt{36+81 }\] \[\LARGE d=\sqrt{117 }\] \[\LARGE d=3\sqrt{13 }\] and we can see that "NEW" (scale or whatever it is, lol) is 3 times bigger... because IF=\(\sqrt{13}\) and DA=\(3\sqrt{13}\) so every "New" side will be 3 times bigger than the old one... I don't know if you've done this (if you've done , it would be better to let me know.. anyway) now let me think about coordinates :)

    lol I got it... here it is.. I counted carefully "distance" between similar sides and I counted "points" where NEXT point could be... so here it is next points would be 12,4 and 6,-5 .... and as long as there's no option for point 12,4 (upper one) you have it (lower one) 6,-5 , I also drew a bit on the photo so it could be more clear.... the answer is C 100% sure... here's the photo : (and sorry for taking so long, I made a mistake at principal , and I had to correct it) ... @lgbasallote see my post, does it looks correct to you or not? :)
