Answer:
The dilation can be represented by (1/3x, 1/3y)
Bobby was correct
Explanations:
Coordinates of Point A = (3, 9)
After dilation:
Coordinates of A' = (1, 3)
Let the scale factor of dilation be represented by k
The relationship between the coordinates is:
1 = 3k or 3 = 9k
Using either of the two relationships, k = 1/3
Therefore, the dilation can be represented by (1/3x, 1/3y)
