Step-by-step explanation:
Substitute the point (-9, -6) into the system of equations:
[tex] - 6 = \frac{1}{3}( - 9) - 3[/tex]
[tex] - 6 = - \frac{1}{3} ( - 9) - 5[/tex]
Simplify by multiplying and subtracting.
[tex] - 6 = - 6[/tex]
Correct.
[tex] - 6 = -8[/tex]
Incorrect.
(-9, -6) is not a solution of the system of equations.
