Parallel lines will always have the same SLOPE. In the case of this equation, the slope is [tex]1[/tex] since [tex]x[/tex] is the same as [tex]1x[/tex] and the coefficient of [tex]x[/tex] is the slope. Because there is no [tex]y[/tex], the graph of the equation will NEVER intercept the y-axis. Therefore, whatever answer option does not have [tex]y[/tex] is correct.
Answer: C. [tex]x=2[/tex]
Here's the graph to help you visualize:
