Question

4 number lines going from negative 2 to positive 2. A has an open circle at negative one-half, everything to the right is shaded. B has a closed circle at negative one-half, everything to the right is shaded. C has an open circle at negative one-half, everything to the left is shaded. D has a closed circle at negative one-half. Everything to the left is shaded. Which graph represents the inequality? y greater-than negative one-half A B C D

Answer 1

A has an open circle at negative one-half, everything to the right is shaded

Explanation:

"y is greater than" mean two things:

• there will be an open circle at the boundary value (the boundary is not included)
• shading will be to the right of the boundary value (including values greater than that boundary)

These match the description of number line A.
