Explanation:

To verify a solution to a system of linear equations in two variables, we need to ensure the values of \(x\) and \(y\) satisfy both equations. A system's solution must make all equations in the system true, not just one. Regraphing is not the standard verification method; substitution into both equations is. So the correct option is the one stating to check both equations.

Answer:

The option: "Check that the values of x and y make both of the equations true."
