First option is correct.

Step-by-step explanation:

The given system of equations is

\(y=-3x+6...(i)\\\\y=9...(ii)\)

We can solve this system of equations by substituting method.

Substitute y = 9 in equation (i)

\(y=-3\cdot9+6\\\\y=-27+6\\\\y=-21\)

Therefore, the solution of the system of equations is (-21,9)

First option is correct.
