Answer:
x < 3
Explanation:
The standard linear equation of a vertical line with an undefined slope is x = a, where "a" represents the x-intercept of the graph. Vertical lines have an undefined slope because it doesn't have any horizontal change.
The given graph represents the graph of a vertical line, whose x-intercept occurs at point (3, 0). Since the graph has a dashed boundary line, then it means that the linear inequality symbol used to represent the graph is "<," which implies that the endpoint, x = 3, is not included as part of the solution. Additionally, since the shaded half-plane region is towards the left-hand side of the boundary line, it means that the solution must less than 3.
Therefore, the linear equation that represents the given graph is x < 3.
