Answer 2

question #23
hint:
we have to find the slope of line D first

Answer 3

ok

Answer 4

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

Answer 5

... of the slope

Answer 6

okZZ>?

Answer 7

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

Answer 8

5/4

Answer 9

Find the reciprocal of 5/4

Answer 10

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

Answer 11

...then stick a negative sign.

Answer 12

the*

Answer 13

okay so for the number 3 ths answer is um B OR A right????

Answer 14

ya

Answer 15

only one is the correct option

Answer 16

But what is the reciprocal of 5/4?

Answer 17

is the answer A??? @Michele_Laino

Answer 18

no, I'm sorry, option A is a wrong option

Answer 19

THEN b

Answer 20

yes but do you know why?

Answer 21

well of all the answers that you have gave me i new that it needed to be a or b !?:?

Answer 22

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?

Answer 23

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).

Answer 24

oh okay i did not know that @calculusxy
