Question

Find the coordinates of U after a dilation about the origin of 1.5. Write your answer in the form (a, b).

Answer 1

U' (1.5, 3 )

Explanation:

since the dilatation is centred at the origin , then multiply each of the coordinates of point U by the scale factor of 1.5

U (1, 2 ) → U' (1(1.5), 2(1.5) ) → U' (1.5, 3 )
