Answer:
B. (x, y) --> (7/2x, 7/2y)
Step-by-step explanation:
I can't tell for sure, so I am assuming the large circle is the image, Circle C', and the small circle is the original circle C.
The radius of circle C is 2 units.
The radius of circle C' is 7 units.
To find the scale of the dilation divide the new size by the old size.
New size: 7 units
Old size: 2 units
scale: 7/2
The scale of the dilation is 7/2.
Answer: B. (x, y) --> (7/2x, 7/2y)
