9x + 3y = -22        |subtract 9x from both sides

3y = -9x - 22          |divide both sides by 3

y = -3x - 22/3

The line parallel to the line y = -3x - 22/3 has that same a slope.

Therefore your answer is B) y = -3x + 8.

9x + 3y = -22     

3y = -9x - 22          

y = -3x - 22/3
slope m=-3
lines are parrallel when m1=m2

m1=-3
 Y = -3x + 8
m2=-3
s0 B is right option
