Find the difference
Answer:
3rd option
Step-by-step explanation:
Since the centre of dilatation is at the origin then multiply the coordinates by
K (- 3, 9 ) → K' (- 3( ), 9(
) ) → K' (- 1, 3 )
L (- 9, 0 ) → L' (- 9( ), 0 (
) ) → L' (- 3, 0 )
M (2, - 8 ) → M' (2 ( ), - 8 (
) ) → M' (
, -
)
N (6, 4 ) → N' (6 ( ) , 4 (
) ) → N' ( 2,
)
