How many solutions does the system of equations below have? y=-3x-7 y=-3x-7 no solution one solution infinitely many solutions

The system of equations provided is: Both equations are identical, which means every solution to the first equation is also a solution to the second equation. Therefore, the system does not have a unique solution; instead, it has infinitely many solutions, as any value of will give a corresponding value of that satisfies both equations simultaneously.
