Answer:
B
Step-by-step explanation:
1. A reflection across the origin has a rule
2. A translation 9 units to the left and 7 units down has a rule
Then the rule for a reflection across the origin followed by a translation 9 units to the left and 7 units down is
This means that the point with coordinates (x,y) has the image with coordinates (x',y')=(-x-9,-y-7).
