Answer

True

Work Step by Step

Parallel lines have the same slope. The slope of a vertical line is always undefined because using the slope equation: $\frac{rise}{run}$, a vertical line has no run. Anything divided by $0$ is undefined. Because both of the vertical lines will have undefined slopes, they must be parallel.
