Answer: x < 2.
- A x < 2
- B x > 2
- C x < 3
- D x > 3
Correct answer: A. x < 2
Explanation: −2x > −4; dividing by −2 reverses the sign to give x < 2.
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.
