Answer: E ; (0,12) , (9,0)
Explanation: To find coordinates by a scale factor is by multiplying.
What we need to do is to multiply the coordinate points by the scale factor.
Find A' is use A 's coordinate. A 's coordinates are (0,4)
3 x 0 = 0
3 x 4 = 12
A' coordinates are : (0,12)
Using the same technique with C'.
3 x 3 = 9
3 x 0 = 0
C' coordinates are : (9,0)
