Answer:

  • a) reduction
  • b) 1/2

Step-by-step explanation:

a) The image A'B'C'D' is smaller than the original ABCD, so the dilation is a reduction. The image is reduced in size from the original.

__

b) Each image point is 1/2 the distance of the original point from the origin. Count the grid squares to see this, or compare coordinates:

  A'(-1, 2) = 1/2·A(-2, 4)

Thus the scale factor is 1/2.
