Find the equation of a line perpendicular to the given line: y = 3x – 1.

Question

anonymous · Answer

so do u know what is the slope of y = 3x - 1?

anonymous · Answer

is it 3x over 1?

anonymous · Answer

but actually speaking you won't get a proper equation -

bcoz if u still find the slope u do not have even one of the co-ordinates of the perpendicular line.

anonymous · Answer

well i dont what its asking me but here are the possible answers y = -1/3x – 1  
   y = 1/3x  
   y = 1/3x – 1  
   y = -3x

anonymous · Answer

oh oh that way. Fine then.

You know the slope of y = 3x-1 ?

anonymous · Answer

no it only says this Find the equation of a line perpendicular to the given line: y = 3x – 1.

anonymous · Answer

oh LOL that is FINE. but to find perpendicular equation, we need to find its slope. how would you do that?

anonymous · Answer

i know you add something to both sides

anonymous · Answer

well actually you DON'T. 

That is why i was asking you of the slope of y = 3x - 1.
