Answer:
option 2
Step-by-step explanation:
consider the coordinates A (- 3, 4 ) and A' (- 1, 
)
since the dilatation is centred at the origin, then corresponding coordinates are multiples/ divisors of each other, then image to original gives scale factor.
scale factor = 
= 
= 
and 
=
similarly B (1, - 2 ) and B' (, - 
)
= and 
=
