Number Line Graph 03153B

1. **State the problem:** You want to graph the solution of the inequality $x < -7$ on a number line. 2. **Draw a horizontal line:** This line represents all real numbers. 3. **Mark the point $-7$ on the line:** Place a point exactly where $-7$ is located. 4. **Use an open circle at $-7$:** Since the inequality is strictly less than ($<$), $-7$ is not included in the solution, so draw an open circle (a hollow dot) at $-7$. 5. **Shade to the left of $-7$:** Shade the line to the left of $-7$ to show all numbers less than $-7$ are included in the solution. 6. **Label the number line if needed:** You can label the point $-7$ and indicate the direction of the shading. This visually represents the solution $x < -7$ on the number line.
