Final answer:
The line is vertical
Step-by-step explanation:
A line with an undefined slope can be represented by a vertical line. This means that the line is completely perpendicular to the x-axis and goes straight up or down. In this case, the line passes through the point (-5, -8). Since the line is vertical, it means the line is also passing through all x-coordinates equal to -5. As a result, option 1) The line is vertical is true.
