Question

What are the coordinates of the image of the point (-3, 6) after a dilation with a center of (0, 0) and scale factor of 1/3?

A. (-9, 18)
B. (-3, 6)
C. (-1,2)
D. (0,0)

Answer 1

C

Explanation:

since the dilatation is centred at the origin then multiply the coordinates of the point by scale factor of
`(1)/(3)`

(- 3, 6 ) → (
`(1)/(3)` (- 3),
`(1)/(3)` (6) ) → (- 1, 2 )
