Question

Use the interactive number line to graph the inequality x > –2.5.

Which statements are true? Check all that apply.
The arrow points to the left.
The arrow points to the right.
The circle is open.
The circle is closed.
x = –2.5 is part of the solution set.

Answer 1

B,C

Explanation:

Answer 2

• The arrow points to the right
• The circle is open

Explanation:

The solution to x > -2.5 includes all numbers larger than -2.5. On a number line, those are the numbers to the right of -2.5. The arrow points to the right to indicate all numbers to the right of -2.5 are included in the solution set.

Because -2.5 > -2.5 is a False statement, x=-2.5 is NOT part of the solution set. That is why the circle at -2.5 is open, not closed.
