Answer: 4.
- A 4
- B 3
- C 2
- D 1
Correct answer: A. 4
Explanation: Only 4 is strictly greater than 3.
One-variable inequalities use open (excluded) or closed (included) circles on a number line; two-variable inequalities use a dashed (strict) or solid (non-strict) boundary line, with the solution being the entire shaded half-plane on one side of it.
Concept context
Solving linear inequalities in one and two variables algebraically and graphically, and representing solutions on a number line or as a region in a plane.
