I assume the rest of the question went something like "what was the scale factor for this dilation"?
Do you see a number that you can multiply each coordinate of the first three points that maps to the coordinates of the 2nd three points?
For example (-1,3) -> (-4, 12). If you divide -4/-1 or 12/3 you get the scale factor (4). Confirm that the same multiplication maps the other two pre-image points to their respective images.
