The system of equations are  

Divide each side of equation (2) by .

Observe the equations (3) and (1) are same.

So the graph of the equations intersect each other at every point.

Therefore, the system has infinitely many solutions.

Since above system has solution, the system is consistent.

And the system has infinitely many solutions., it is dependent.

Infinitely many solutions.

The system is consistent, dependent.
