Answer:
The correct option is A) x = 3
Explanation:
Consider the provided graph.
In the graph of a vertical line, x only takes one value.
The equation for a vertical line is x = a,
where a is the value that x takes.
Now consider the provided graph.
The graph shows a vertical line and 3 is the value that x takes.
Hence, the equation of line is x = 3
Therefore, the correct option is A) x = 3
