Dilate the ordered pair (2, 4) with the scale factor of… k = 4 k = 3 (8, 16) (6, 12) (1, 2)

Dilate the ordered pair (-8, 0) with the scale factor of… k = 1 k = 2 k = 0.25 (-8, 0) (-16, 0) (-2, 0)

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? 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? The ordered pair (4, 1) is dilated and is now located at point (12, 3). What scale factor was used for the dilation? (6, 6) (-3, 3) (0, -6) k = 3 (8, 16)

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 = 50
