1. Problem Description
The problem asks to graph the inequality on a number line. We need to identify the correct endpoint (open or closed circle) and the direction of the arrow representing the solution set.
2. Solution Steps
The inequality is .
* Endpoint: Since the inequality is (strictly greater than), we use an open circle at to indicate that is not included in the solution set.
* Direction: The inequality means that can be any number greater than . Therefore, we need to draw an arrow to the right (positive direction) from the open circle at .
3. Final Answer
The graph of the inequality is an open circle at with an arrow pointing to the right.
