How to fill out inequalities and numbers lines

How to fill out inequalities and numbers lines

1. To fill out inequalities, follow these steps:
2. Start by writing the inequality with the variable on one side and the constant on the other side.
3. Solve the inequality for the variable, just like you would solve an equation. Remember to reverse the inequality sign if you multiply or divide both sides by a negative number.
4. Graph the solution on a number line. Use an open circle for strict inequalities (< or >) and a closed circle for inclusive inequalities (≤ or ≥).
5. Shade the region on the number line that represents the solution. If it's a strict inequality, the shading should be on one side of the circle. If it's an inclusive inequality, the shading should cover the entire region up to the circle.
6. To fill out number lines, follow these steps:
7. Determine the range of numbers that need to be represented on the number line.
8. Mark the endpoints of the range as the first and last points on the number line.
9. Divide the range into equal intervals and label the points accordingly. The size of the intervals depends on the scale of the number line.
10. Place any specific numbers or values at their corresponding positions on the number line.
11. If there are any inequalities or conditions, mark them on the number line using open or closed circles along with arrows to indicate the direction.
12. The number line is now filled out and can be used to represent the given information.
