Solve the system. State whether the system is inconsistent or has infinitely many solutions. If the system has infinitely many solutions, write the solution set with y arbitrary.
81x - 9y = 45
-9x + y = 5
Select the correct choice below and, if necessary, fill in the answer box to complete your choice
A. There is one solution. The solution set is {\boxed{}}
(Simplify your answer. Type an ordered pair.)
B. The system has infinitely many solutions. The solution set is {\boxed{}}
(Simplify your answer. Type an ordered pair. Type an expression using y as the variable.)
C. The solution is inconsistent.
