Answer:

C. There are infinitely many solutions.

Explanation:

If the graphs of linear equations are the same line, then any point (solution) on one line is automatically a point on the "other" line. For example,


\begin{array}{l} x + y =10 \\ 2x + 2y =20 \end{array}

The graphs of these "two" equations is only one line, x + y =10. The point
(5, 5)is on "both" lines.
