A square has a vertex at (4, 8) on the coordinate plane, and it is dilated by a scale factor of 2. Where is the dilated vertex going to be located? (8, 16) A triangle has vertices at (2, 2), (-1, 1), and (0, -2). The triangle is dilated by a scale factor of 3. Where are the dilated vertices located? (6, 6) (-3, 3) (0, -6) The ordered pair (4, 1) is dilated and is now located at point (12, 3). What scale factor was used for the dilation? k=3

Find the scale factor if the preimage point is (12, 4) and the image is (3, 1) Find the scale factor of the dilation: Ben is wanting to build a model rail car that is 1 foot in length. The actual length of a rail car is 50 feet in length. What is the scale factor that Ben needs to use to make sure his model rail car is accurate? k = 1/50
