Question

Write a rule to describe each transformation

Answer 1

Answer:

  (x, y) → (1.5x, 1.5y)

Step-by-step explanation:

Each of the image coordinates is 1.5 times the corresponding pre-image coordinate. The transformation is a dilation by a factor of 1.5 about the origin.

Some authors use a notation like D(1.5,O) to indicate the transformation. I like the one shown above, or ...

  (x, y) → 1.5(x, y)
