Question

will give medal and fan! help please?(:

Answer 1

@marybel86

Answer 2

@hartnn

Answer 3

can u find slope given 2 points ?

Answer 4

\(\large m= \dfrac{y_2-y_1}{x_2-x_1}\)
where, x1,y1 = 1,3
x2,y2 =3,17
just plug in values!

Answer 5

Oh so 17- 3/ 3-1 ? @hartnn

Answer 6

yes!
so, m=... ?

Answer 7

whats 17-3=... ?

Answer 8

14 :)

Answer 9

do you now do 14/2 ? @hartnn

Answer 10

so, m = 14/2 =... ?

Answer 11

7 ? (:

Answer 12

aren't the lines perpendicular?

Answer 13

yup!

Answer 14

so that would mean 7 isn't your final answer, but it looks like you know what you're doing

Answer 15

wait so then do i sq root it?

Answer 16

if m is the slope of one line

then -1/m is the slope of the line perpendicular to that first line

Answer 17

ex: if 2/3 is the slope of one line, you flip the fraction and the sign to get -3/2

So -3/2 is the slope of the perpendicular line (it's perpendicular to the line with a slope of 2/3)

Answer 18

\[m_1*m_2=-1\]

Answer 19

oh so its like - 2/14 instead? (:

Answer 20

which reduces to ???

Answer 21

negative reciprocal :) found it!

Answer 22

sorry. i lost connection :(

Answer 23

-0.14

Answer 24

keep it as a fraction though

Answer 25

reduce it as much as possibl

Answer 26

possible*

Answer 27

what's - 0.14 as a fraction? (:

Answer 28

reduce -2/14
how many times 2 goes into 14 ?

Answer 29

14 times?

Answer 30

really ?
i thought 7 times..
