<reasoning>

Identify the inequality and boundary point

\[
x > 67
\]

Determine the endpoint style

\[
\text{Strict inequality } (>) \implies \text{Open circle at } x = 67
\]

Determine the direction of the ray

\[
x > 67 \implies \text{Shade to the right of } 67
\]
</reasoning>

<answer>
To graph the inequality \(x > 67\) on the number line:

1. Place an open circle at \(67\).
2. Draw a ray pointing to the right from \(67\).
