Given the graph of a vertical line with an undefined slope, where its x-intercept occurs at point, (5, 0). 
The linear inequality that represents the graph is x > 5.  We use the inequality symbol, ">" instead of "≥" due to the dashed line on the graph. This implies that the endpoint, x = 5 is excluded as an interval. 
Therefore, the linear inequality of the graph is x > 5.
