Okay
18,377
29
[]
volunteer
cool
18,377
30
[]
volunteer
now C
18,377
31
[]
volunteer
-1,-2
18,377
32
[]
student
Help me with that one please!
18,377
33
[]
volunteer
x= -1 (left of zero) and y = -2 (down below zero)
18,377
34
[]
volunteer
in RED you see it
18,377
35
[]
student
Yes I do
18,377
36
[]
volunteer
now slope (AB) = 4-6/(3-0)
18,377
37
[]
volunteer
(4-6)/(3-0) = -2/3 | let me know if you understood it
18,377
38
[]
student
Yes I did
18,377
39
[]
volunteer
cool
18,377
40
[]
volunteer
That applies to all sloped
18,377
41
[]
volunteer
slopes
18,377
42
[]
student
Okay
18,377
43
[]
volunteer
do you see the formula on the board
18,377
44
[]
student
No
18,377
45
[]
volunteer
now
18,377
46
[]
volunteer
it is derived from pythogras theorm
18,377
47
[]
student
The m represents the length right?
18,377
48
[]
student
(that's what our teacher said)
18,377
49
[]
volunteer
yes measure
18,377
50
[]
student
Okay
18,377
51
[]
volunteer
2^2 + -3^2 = 4 + 9 = 13
18,377
52
[]
volunteer
did that help?
18,377
53
[]
student
Yeah
18,377
54

Question
18,377
61
[]
volunteer
Any other help
18,377
62
[]
student
Where did you get all these numbers from?
18,377
63
[]
volunteer
which ones?
18,377
64
[]
volunteer
the coordinates are given
18,377
65
[]
volunteer
A(0,6)
18,377
66
[]
student
No You square Not those 2^2 3^3
18,377
67
[]
volunteer
oh A(0,6) and B(3,4) | = sqrt [(6-4) ^2 + (0-3)^2] = 4 + 9 = sqrt(13)
18,377
68
[]
student
So that's the side of side A and B?
18,377
69
[]
volunteer
yes
18,377
70
[]
volunteer
m(CB) = sqrt(52)
18,377
71
[]
volunteer
you will find AB = DC and AD = BC
18,377
72
[]
volunteer
I can wait till you solve it. OK :-)
18,377
73
[]
student
You're so nice thank you!
18,377

[]
volunteer
I have trick for you.
18,377
97
[]
student
Okay what is it???
18,377
98
[]
volunteer
if line travels up or right slope is +ve
18,377
99
[]
volunteer
else negative
18,377
100
[]
student
Oki thanks
18,377

Slope of AB 3/2?
18,377
102
[]
volunteer
for this one or previous
18,377
103
[]
student
This one
18,377
104
[]
volunteer
(4-0)/(2-1)
18,377
105
[]
volunteer
change in y / change in x
18,377
106
[]
student
Is it 4/3?
18,377
107
[]
student
Hold on Brain isn't working
18,377

Help
18,377

117
[]
student
Like rise/run
18,377
118
[]
volunteer
let me see
18,377
119
[]
volunteer
change in y = 4
18,377
120
[]
volunteer
sorry A point is wrong
18,377
121
[]
volunteer
(1,0)
18,377

Yes, teacher is right
18,377
125
[]
volunteer
so now you see 4/1
18,377
126
[]
volunteer
change in y/x
