Consider the line whose equation is y = - 1/5x + 3. The slope of any line that is parallel to this is. The slope of any line that is perpendicular to this is.

Parallel slope = - 1/5Perpendicular slope = 5

Parallel lines have the same slope, but different y intercepts.

Perpendicular lines have slopes that multiply to - 1 (assuming neither line is vertical). So if m is the perpendicular slope of - 1/5, then (-1/5) * m = - 1 solves to m = 5. Another way to look at it is to flip the fraction and the sign of - 1/5 to get to 5/1 or just 5.
