Solve and Graph Inequalities

When you graph an inequality, you use a solid line when you use which symbols?

• ≤, ≥

• <, >

When you graph an inequality, you shade the bottom portion of the graph when you use which symbols?

• ≤, <

• ≥, >

Which ordered pair is NOT a solution to the system of inequalities graphed?

• (-2, 2)

• (0, 2)

• (1, 2)

• (-3, 6)

Locate (4, 8) on the graph. Why is (4, 8) NOT a solution to the system graphed?

• (4, 8) is a solution for only the blue inequality.

• (4, 8) is a solution for only the red inequality.

• (4, 8) is in the common shaded region.

• (4, 8) is in the unshaded region.
