Question

Write an inequality for each graph.

1)

-8 (open circle) to 11 (closed circle)

2)

-15 (closed circle) to 5 (closed circle)

Answer 1

x = unknown number (that is a solution/makes the inequality true)

When the inequality sign is </> (less than/greater than), the dot is an open circle.

When the inequality sign is ≤/≥ (less than or equal to/greater than or equal to), the dot is a closed circle.

14.) The line has an open circle on -8, and a closed circle on 11.

-8 < x ≤ 11 [x is any number greater than -8 and less than or equal to 11]

15.) The line has a closed circle on -14 and 5.

-14 ≤ x ≤ 5 [x is any number greater than or equal to -14 and less than or equal to 5]
