**Reiny**, Monday, November 4, 2013 at 4:05pmFind the slope of the line joining your two given points (you should know how to do that)

A line parallel will have the same slope

A line perpendicular will have a slope which is the negative reciprocal of the given slope

let me know what you get

Parallel is 5 or 1/5

Perpendicular is -5

**Reiny**, Monday, November 4, 2013 at 4:49pmyour slope of the given line is correct as 5

Then a parallel line also has a slope of 5

a perpendicular line will have slope of -1/5

your statement of

"Parallel is 5 or 1/5" is illogical.

same for " perpendicular is -5" , makes no sense to me.

Perpendicular is a property, -5 is a quantity

That is like saying " funny is -5"
