The answer would be a. shifted three units right and two units up
This is easy to solve as long as you approach it the right way. The easiest way to solve this would be to find one point and count how many it moved in each direction to get to the new point. I used B in this one, is moved from (2, 5) to (5, 7)
Which is 3 (from 2 to 5) on the x axis and 2 (from 5 to 7) on the y axis
Hope this helps!
