5

Answer 1

Step-by-step explanation:

Substitute the point (-9, -6) into the system of equations:

$- 6 = \frac{1}{3}( - 9) - 3$

$- 6 = - \frac{1}{3} ( - 9) - 5$

Simplify by multiplying and subtracting.

$- 6 = - 6$

Correct.

$- 6 = -8$

Incorrect.

(-9, -6) is not a solution of the system of equations.
