Answer:
(-2, -9)
explanation:
original coordinates of B: (7, 9)
use the formula: (x, y) ---> (x, -y)
- if reflects over x-axis new coordinates: (7, -9)
If horizontally shifted there will be change in x axis,
- new coordinates (7-9,-9) → (-2, -9)
You do 2 times 12 and 2 times 10. And that's 24+20 and that'll get you to 44 :)
I think it would be continuous.
