suppose you use the rule (3x+1,3y4) to transform the original figure into a new figure. How would the side lengths of the new figure compare to the side lengths of the original? I need help fast. Thank you so much.

The homothetic factor is 3, so this is the ratio of the sides of the image compared to the original.
