Answer 2

Do you have a formula for scale factor?

Answer 3

No :/

Answer 4

The scale factor is \(\dfrac{mOA'}{mOA}\) if the centre of dilation is the origin.
If A' is in the opposite quadrant, it is considered negative (not in this case, A and A' are both in the first quadrant).

Answer 5

So will it be A?

Answer 7

I prefer to check your answer numerically than the options because I would like you to focus on the answer than the choice.
Can you please tell me the quotient of mOA' divided by mOA, looking at the graph?
