Part 1 out of 3
A square on the coordinate plane has vertices at
(−3, 3), (3, 3), (3, −3),
and (−3, −3).
A dilation of the square has vertices at
(−9, 9), (9, 9), (9, −9),
and (−9, −9).
Find the scale factor and the perimeter of each square.
Please help me out asap I don't understand how to find the scale factor ;-;
