From a graph, explain how you would identify a consistent system of equations, an inconsistent system of equations, and a dependent system of equations.

Fill in the blank with an appropriate word, phrase, or symbol(s). When solving a system of linear equations, if you obtain a true statement such as 0=0 or 6=6, the system is dependent and has a(n) _ number of solutions.
