scale factor is ditance of the image from the cetre of enlargement / distance of the object from centre of enlargement
so take the distance of the Image from E to be " d " .... and hence the distance of the of the Object from E is d -9 ( 10 - 1 = 9 )
scale factor =4
4= d/ d-9
4 (d - 9) = d
4d -36 = d
4d - d = 36
3d = 36
d =12
so the distance of the image from E is 12 ..... u subtract 12 from 10 = -2
so e ( -2 , 3 )
I didn't ask for this. :p I asked for PT. Never mind, I got it. Can you solve aiii? Finding the coordinates of S?
