Question

x>a plot an circle on a and draw an arrow to the right.

Answer 1

To create a visual representation of the expression \( x > a \):

1. **Draw a number line**:
- Draw a horizontal line and mark it with important points such as \( a \).

2. **Indicate the point \( a \)**:
- Place a circle (open circle) at the point \( a \) to show that \( a \) is **not included** in the solution (since \( x > a \)).

3. **Draw an arrow to the right**:
- From the open circle at \( a \), draw an arrow pointing to the right to indicate that the values of \( x \) extend to infinity beyond \( a \) (i.e., \( x \) can be any value greater than \( a \)).

### Visual Representation:
```
<----|----|----|----|----|----|----|----|----|----|---->
a (------->) x > a
```
In this representation:
- The open circle at \( a \) denotes that the point is not included in the solution.
- The arrow extending to the right indicates that all values greater than \( a \) are part of the solution set of the inequality \( x > a \).
