Problem 7
Graph the inequality y ≥ -3x + 2. Using the test point (0,0), determine which side should be shaded.
A
Shade the region that does NOT include (0,0) because 0 ≥ 2 is false.
B
Shade the region that includes (0,0) because it always simplifies shading to choose the origin when possible.
C
Shade both sides of the line because the inequality is weakly greater-than (≥) and therefore ambiguous.
D
Do not shade anything because the inequality involves a negative slope and negative slopes require special handling.
