Observe the number line and identify the direction of the arrow. The arrow points to the left, indicating values less than a certain number.
Look at the point where the arrow stops or changes direction. Here, the arrow stops at 1.
Check if the point at 1 is included or excluded. The point at 1 is an open circle, meaning 1 is not included in the solution.
Translate this information into an inequality. Since the arrow points to values less than 1 and does not include 1, the inequality is \(x < 1\).
Confirm that the inequality matches the graph: all values less than 1, excluding 1, are represented by \(x < 1\).
