AlgebraEasyInequality from a closed dot and left shading
Algebra practice question
A number line shows a closed dot at −1 with shading to the left of it. Which inequality is graphed?
- A. x ≤ −1Correct
- B. x < −1
- C. x ≥ −1
- D. x ≤ 1
Answer: A. x ≤ −1
A closed dot includes −1, and shading left means smaller values.
Why the other answers are wrong
- B. x < −1
- An open dot would be needed to exclude −1.
- C. x ≥ −1
- Shading right would show ≥.
- D. x ≤ 1
- The dot is at −1, not 1.
