Question

is (-9, -6) a solution to this system of
y = \frac{2}{3}x + 9
y = -\frac{2}{3}x - 12
yes no

Explanation:

Step1: Check first equation

Substitute \( x = -9 \), \( y = -6 \) into \( y=\frac{2}{3}x + 9 \).
Left side: \( y=-6 \)
Right side: \( \frac{2}{3}\times(-9)+9=-6 + 9 = 3 \)
Since \( -6
eq3 \), it fails the first equation.

Answer:

No
