Answer:
b=r-9/9
Step-by-step explanation:
First you do the distributive property...
r=9b+9
then you subtract the 9
r-9=9b
then you divide the 9
r-9/9=b
and because of the symetry property you can flip it...
b=r-9/9

Now we shift seven units to the right,

Now down five,

There it is.
Answer: reflection thru x axis, vertical scale 2/3, right shift 7, down 5, second choice
