Identify the Region That Is the Solution of a System of Inequalities

Locate (1, 2) on the graph. Why is (1, 2) NOT a solution to the system of inequalities graphed?

• (1, 2) is on a dashed line.

• (1, 2) is on a solid line.

• (1, 2) is in the common shaded region.

• (1, 2) is only in one shaded region.

• dashed line, shade above

• dashed line, shade below

• solid line, shade above

• solid line, shade below

Which ordered pair is a solution to the system graphed?

• (-1, 0)

• (4, 4)

• (-4, 4)

• (0, 0)

If an ordered pair lies directly on a solid line AND touches the common shaded region, then the ordered pair _______________ to the system of inequalities.

• is a solution

• is not a solution

Locate (2, 2) on the graph. Why is (2, 2) NOT a solution to the system graphed?

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

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

• (2, 2) is in the common shaded region.

• (2, 2) is in the unshaded region.

If you are asked graph this inequality, how should you shade?

• I should shade above the solid line.

• I should shade below the solid line.

If you are asked to graph this inequality, how should you shade?
