If the slope is -3 what is the parallel slope? What is the perpendicular slope

A line that is parallel to another line will have the same slope as the original. A line that is perpendicular to another line with have a slope that is the opposite reciprocal of the original.

Original: -3 / 1

Parallel (same): -3 / 1

Perpendicular (opposite reciprocal): 1/3

Hope this helps!! :)
