Systems of Inequalities-8th Grade Algebra
posted by Marta .
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.
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.
I don't know how to do these things though.
Is there like a step-by-step process in doing it ??
I D K!
