Answer:
B
Explanation:
1. A reflection across the origin has a rule
![(x,y)\rightarrow (-x,-y).](https://img.qammunity.org/2020/formulas/mathematics/college/fb7yup3jdry8rruwhbg9mc9t3mv0vymgtl.png)
2. A translation 9 units to the left and 7 units down has a rule
![(x,y)\rightarrow (x-9,y-7).](https://img.qammunity.org/2020/formulas/mathematics/college/931xrrr2zctozha7jpd55lu9nb12big8p3.png)
Then the rule for a reflection across the origin followed by a translation 9 units to the left and 7 units down is
![(x,y)\rightarrow (-x-9,-y-7).](https://img.qammunity.org/2020/formulas/mathematics/college/wllp2jk5qq9zmwgbrx17c9k1aq8p5fga0j.png)
This means that the point with coordinates (x,y) has the image with coordinates (x',y')=(-x-9,-y-7).
