- Solve the inequality: Distribute and combine like terms on each side: . Subtract from both sides: . Divide both sides by . The divisor is positive, so the symbol does not change: .
- Choose open or closed circle (strict vs. inclusive): is strict, so the boundary value is not a solution: draw an OPEN circle at .
- Choose the ray direction (test a point): Test : is true, so shade the ray toward the right.
- Graph on the number line: Open circle at with the ray shaded to the right.
