Step-by-step explanation:

Well there’s no picture for me to go off of so I will give you an easy enough explanation of what I think this is supposed to be.

You’re basically going to go left side three points and down five for every point on the graph (aka ABC) and once you do that label the abc marks with an apostrophe like so; A’B’C’ for every time you change places (I think this is mostly accurate so good luck)
