Answer: D.
The open circle means it could be equal to the starting number
X-axis = A (-7,-3) B (-7,-10) C (-1,-3) first they changed to the x-axis which is this. Just so you know on the x-axis the x-axis stay and the y-axis changed which is this.
When they reflect again on the y-axis the verter of A' is
A' (7, 3) = answer
On the y-axis the y- axis doesnt change but the x-axis changed.
Hope this help!

Answer:
for ![n > 1](https://tex.z-dn.net/?f=n%20%3E%201)
Step-by-step explanation:
Given
-- First Term
--- half common difference
Required
Find the recursive rule
First, we calculate the common difference
![\frac{1}{2}d = 4](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dd%20%3D%204)
Multiply through by 2
![2 * \frac{1}{2}d = 2 * 4](https://tex.z-dn.net/?f=2%20%2A%20%5Cfrac%7B1%7D%7B2%7Dd%20%3D%202%20%2A%204)
![d = 8](https://tex.z-dn.net/?f=d%20%3D%208)
The second term of the sequence is:
![f(2) = 3 + 8 = 11](https://tex.z-dn.net/?f=f%282%29%20%3D%203%20%2B%208%20%3D%2011)
The third term is:
![f(3) = 11 + 8 = 20](https://tex.z-dn.net/?f=f%283%29%20%3D%2011%20%2B%208%20%3D%2020)
So, we have:
![f(1) = 3](https://tex.z-dn.net/?f=f%281%29%20%3D%203)
![f(2) = 3 + 8](https://tex.z-dn.net/?f=f%282%29%20%3D%203%20%2B%208)
Substitute f(1) for 3
![f(2) = f(1) + 8](https://tex.z-dn.net/?f=f%282%29%20%3D%20f%281%29%20%2B%208)
Express 1 as 2 - 1
![f(2) = f(2-1) + 8](https://tex.z-dn.net/?f=f%282%29%20%3D%20f%282-1%29%20%2B%208)
Substitute n for 2
![f(n) = f(n-1) + 8](https://tex.z-dn.net/?f=f%28n%29%20%3D%20f%28n-1%29%20%2B%208)
Similarly:
![f(3) = 11 + 8](https://tex.z-dn.net/?f=f%283%29%20%3D%2011%20%2B%208)
Substitute f(2) for 11
![f(3) = f(2) + 8](https://tex.z-dn.net/?f=f%283%29%20%3D%20f%282%29%20%2B%208)
Express 2 as 3 - 1
![f(3) = f(3-1) + 8](https://tex.z-dn.net/?f=f%283%29%20%3D%20f%283-1%29%20%2B%208)
Substitute n for 3
![f(n) = f(n-1) + 8](https://tex.z-dn.net/?f=f%28n%29%20%3D%20f%28n-1%29%20%2B%208)
Hence, the recursive is:
for ![n > 1](https://tex.z-dn.net/?f=n%20%3E%201)
