The system of equations 2x + 4y = 6 and 4x + 8y = 8 is

- Consistent with a unique solution
- Consistent with infinitely many solutions
- Inconsistent
- None of the above

**Answer**

When there is no solution, the equations are called inconsistent. This happens, when the lines are parallel.

Here, a_{1}/a_{2} = b_{1}/b_{2} = 1/2 ≠ c_{1}/c_{2}

So, the two lines are parallel.

**The correct option is C.**
