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 =
SLOPE IS -3
4-7 over 0-(-1)
Undefined
m = Δy / Δx
m = (12 − -8) / (-6 − -6)
m = 20 / 0
m = undefined
The slope is undefined.
4/9 or 44.4%
