Question

X=-42 what slope if a line is perpendicular to it and what slope of the line is parallel

Answer 1

Parallel is undefined

Perpendicular is 0

Explanation:

The line x = -42 is a vertical line through the x-axis. As such its slope is undefined. All parallel lines have the same slope and will also be undefined. Perpendicular lines will be lines horizontal through the y-axis. This means the slope of any perpendicular line to it will be 0.
