I asked a question about Parallel lines earlier how do i do perpendicular ones?

Find the equation of the perpendicular line to each of the following that passes through the point indicated.
x = -5 passing through the point (-1,- 6)

lgbasallote · Answer

perpendicular line is negative reciprocal slope of the given line

anonymous · Answer

prity much

anonymous · Answer

So it'd be like 5 for this one? like opposite?

anonymous · Answer

the slope of the perpendicular line  times the slope of the parrallel line equals -1

anonymous · Answer

just flip 5/1over and change the sighn

lgbasallote · Answer

close...you have to take the reciprocal of 5

lgbasallote · Answer

wait...why 5?

anonymous · Answer

thats fliping it over right

lgbasallote · Answer

x = 5 is a vertical line...so the perpendicular line should be a horizontal line

make sense

anonymous · Answer

that woukd be the slope

lgbasallote · Answer

so the perpendicular line would look something like 

y = something

lgbasallote · Answer

got it @Lunarwolf58 ?

anonymous · Answer

but the slope wold be 0

lgbasallote · Answer

no...slope of vertical line is undefined

anonymous · Answer

Its making more sense trying to work it out now

anonymous · Answer

that would make sence since they does not cange

lgbasallote · Answer

go for it :D

anonymous · Answer

the y not yhey
