Finding Original Coordinates (Pre-Image)

Work backward from a dilated image to determine the coordinates of the original pre-image. Use the scale factor and image points to calculate original coordinates.

Questions

  1. MultiChoice

    If the image point A' is (8, 12) after a dilation with k = 2 centered at origin, what was pre-image A?

  2. MultiChoice

    Image point B' is (-5, 3) after dilation with k = 1/3 centered at origin. What was B?

  3. MultiChoice

    The point C' (3, -4) was produced by a dilation centered at the origin with k = 0.5. Find pre-image C.

  4. MultiChoice

    D' is at (9, 15) after a dilation centered at origin with scale factor k = 3. What is D?
