Question

Write a translation rule for the circles: (x, y) ->

Answer 1

The centre of the first circle (small) is (3,7)

The centre of the second circle (big) is (3,2)

Since the x co-ordinate is same no translation occured horizontally

The y co-ordinate reduced by 5 so the translation was 5 unit down along y-axis.

Hence the translation that occured is:

`(x,y)=(0,-5)`

Hence (0,-5) is the translation value.
