Answer: A solid line.
- A A dashed line
- B A solid line
- C No line is drawn
- D A curved line
Correct answer: B. A solid line
Explanation: Since the inequality includes equality (<=), the boundary line is solid, meaning points on the line are included.
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.
