Solve system of equations by graphing then classify as Independent on dependent and consistent or inconsistent?

Without any work, I can see that each line has a slope of 1/3.
So you will have two parallel lines, which of course will not meet.
So what classification would the system fall under?

Consistent and independent?

Yes, they are independent, because one equation cannot be derived from the other.
But they are inconsistent, since there is no solution.
