IS THAT A, PL CONFIRM

Question

Which set of transformations is represented by (x,y)+(-x+1, -y+2)? 

a 180° counterclockwise rotation about the origin followed by a translation 1 unit to the right and 2 units up 

a 90° counterclockwise rotation about the origin followed by a translation 1 unit to the left and 2 units up 

a 90° clockwise rotation about the origin followed by a translation 1 unit to the right and 2 units up 

a 180° clockwise rotation about the origin followed by a translation 1 unit to the left and 2 units up 

Answer 1

Hi Humar,

You are correct! Now there is some missing information like would x and y be the same number or would it be the same number. Aside from that, I used a common point of (4,4). Applying the second expression, I got the endpoint (-3,-2). After applying each transformation & translation for, each choice, (A) seems to be the correct answer.

I did another example of my starting point (3,5), and my endpoint after doing the transformation and translation was (-2,-3). After testing all the answer choices, I can say that answer choice (A) is the correct solution to this problem, and I can confirm that!
