Given that the solution set to a system of three linear equations is a line, which of the following is true about the system? the system can be either inconsistent or consistent. the system can be either independent or dependent. the system can only be independent and consistent. the system can only be dependent and consistent.

The option (d) is correct i.e. The system can only be dependent and consistent.

The solution is consistent when at least one solution is possible. And a consistent set of equations has infinitely many solutions, then it is called dependent equations.
Since here, all the three lines have one solution, i.e. they are consistent and dependent.
