Find the slope of Line D and to find the slope of the perpendicular line, take the negative reciprocal.

the slope m, of line D, is: \[\Large m = \frac{{6 - 1}}{{5 - 1}} = ...?\]

Find the reciprocal of 5/4
Michele_Laino
  • Michele_Laino
correct! now the requested slope m1, is given by thie condition: \[\Large {m_1} \cdot \frac{5}{4} = - 1\]

okay so for the number 3 ths answer is um B OR A right????
calculusxy
  • calculusxy
ya
Michele_Laino
  • Michele_Laino
only one is the correct option
calculusxy

But what is the reciprocal of 5/4?
NathalyN
  • NathalyN
is the answer A??? @Michele_Laino
Michele_Laino
  • Michele_Laino
no, I'm sorry, option A is a wrong option
NathalyN
  • NathalyN
THEN b
calculusxy
  • calculusxy
yes but do you know why?
NathalyN
  • NathalyN
well of all the answers that you have gave me i new that it needed to be a or b !?:?
Michele_Laino
  • Michele_Laino
If I multiply both sides of my equation by 4 , I get: \[\Large {m_1} \cdot 5 = - 4\] please divide both sides by 5, what do you get?
calculusxy
  • calculusxy
Remember that finding the perpendicular line of a line that we already know, we need to find the slope first (of the original line). Then, we have to find the reciprocal (a/b -> b/a) and finally put a negative sign next to it (that's why it's called negative reciprocal).
