Systems of Inequalities8th Grade Algebra
posted by Marta on .
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 ≥ x3 AND y ≥ 9  x
the one "tilting" west:
y ≤ 9  x AND y ≥ x  3
You try the rest. 
I don't know how to do these things though.
Is there like a stepbystep process in doing it ?? 
I D K!

5x+3y>9
