Graph the equation. The graph will divide the coordinate plane into four reqions. Write a system of inequalities that describe each region. Labe the region with these inequalities.

1) y = x - 3
y = 9 - x

I already graphed it,
I only need help on writing the systems of inequalites in each regiopn.
HELP?

the one "tilting" north :
y ≥ x-3 AND y ≥ 9 - x

the one "tilting" west:
y ≤ 9 - x AND y ≥ x - 3

You try the rest.
