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

  • Algebra -

    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?

  • Algebra -

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