Explanation:
what do you not understand here ? please let me know, how I can help further.
just look at the coordinates of the vertexes.
the same change happens to each one in the same way.
each point is an ordered pair of (x, y) coordinates.
changes to the x-coordinate moves the point left or right.
changes to the y-coordinate moves the point up or down.
so, we can see here, from I to H every x-coordinate was increased by 8.
and every y-coordinate was decreased by 3.
so, the translation was right 8 units and down 3 units.
