Start with choice A. Compare the coordinates of each new point with the original point. Make sure the same was done to both coordinates of all points

Then follow onto choice B, whatever works; is your answer. (:

we discussed this before If it is a dilation about the origin then all values will be multiplied by the |SAME factor you can see in the first one J(6,7) => J' (6,21) does NOT meet that at x is multiplied by 1 but y is multiplied by 3 have a look at all the answers and find one where the transform has a common factor for all points...

well done - that's a habit worth acquiring :-)

do i still do the same if the corrdinates are negative?
MrNood
  • MrNood
yes (remember to keep the negative sign after you multiply
