Question

Complete the equation of the graphed linear function in point-slope form.

y – 6 = (x – )

The graph of the function goes through point negative 6, 6 and point negative 8, 2.

Answer 1

@TheSmartOne

Answer 2

y – 6 = (2-6)/(8-6)(x –6 )

Answer 3

Im confused :/

Answer 4

@borak

Answer 5

you have to fill :-
y-y1 = m(x-x1);

Answer 6

im confused on how to do that

Answer 7

y1=6 then you go to the see what the x is belong to y1=6

Answer 8

y1?

Answer 9

then you find (x1,y1)

Answer 10

just symbol y1

Answer 11

im so confused. im so sorry

Answer 12

o.k lets begin from start

Answer 13

okay

Answer 14

you have somthing like that
y -6 = (x- )

Answer 15

yes

Answer 16

the linear function =
y -6 = m(x-x1)
the point that substitue in this function is (x1,6) and m is the slope

Answer 17

okay

Answer 18

Slope for the line is given by
m= (y1-y)/(x1-x)

where yx1,y1 are the points on the line -6,6

now calculating slope of the line... i.e. m
consider any 2 points on the line (refer graph)
(-6,6) and (-10,-2)

therefore, slope will be m = [-10 - (-6)]/ [-2 - 6] = -4/-8 = 1/2

so you have m = 1/2, (x1,y1) as (-6,6) and the formula
m=(y-y1)/(x1-x)

Answer 19

okay now i am even more confused then i already was O.O

Answer 20

you can look in the attached picture an tell me what

Answer 21

the Point is at -6,6?

Answer 22

depending in the linear function in picture what (x1,6) when y=6

Answer 23

yea

Answer 24

when find x1 in the linear function
y-6 = m(x- (-6)) =

Answer 25

then we left to find m or the slope

Answer 26

(-6,6) is te point

Answer 27

so i need to find the slope?

Answer 28

yes and you solve the problem

Answer 29

let's take 2 points (-8,2) and (-6,6)

Answer 30

can you find the slope from these 2 points

Answer 31

would the slope be -6?

Answer 32

or -1?

Answer 33

delta {y}/delta{x}
(6-2)/(-6 -(-8)) = 4/2 = 2

Answer 34

delta?

Answer 35

delta{y} = y1-y2 // y1 y in first point and y2 is the y in second p[oint

Answer 36

\[\Delta{y}/\Delta{x}\]

Answer 37

im not quite understanding...

Answer 38

what the slope mean do you know ?

Answer 39

it's mean the rate of change in y dpending on change of X

Answer 40

and calcualte him (slope ) = (y1-y2)/(x1-x2);
// the order is imporatnt

Answer 41

2/4

Answer 42

?

Answer 43

4/2 , the y is up and x is down

Answer 44

(-8,2) (-6,6)

Answer 45

this is the 2 points (x,y)

Answer 46

so how would i put that into the equation?

Answer 47

y-6=4(x-2)?

Answer 48

we know that the point that choosed is (-6,6)

Answer 49

so it would be Y-6=4(x-(-6))?

Answer 50

yea

Answer 51

can you give me the last answer ?

Answer 52

Was that the last answer?

Answer 53

sorry ! nothing

Answer 54

I write in wrong place

Answer 55

oh...did i get it right though?

Answer 56

no :D

Answer 57

ughh

Answer 58

the slope is 2 not 4

Answer 59

when we say
6-2/(-8 -(-6)) = 4/2 =2;

Answer 60

so it would be y-6=2(x-4)

Answer 61

y- 6 = 2(x+6)

Answer 62

the point (4,6) not inthe line

Answer 63

the line dont decripte it (4,6)

Answer 64

but the equation has a x- i cant change it to x+

Answer 65

we choose inthe formula the point/points the line descripte them

Answer 66

formula of the linear with (-)

Answer 67

the formula of the linear function
y-y1 = m(x-x1) // m slope , and (x1,y1) points IN THE LINE

Answer 68

so it would be y-6=2(x-6)

Answer 69

(6,6) not point inthe line

Answer 70

there is minus from the fromula itself

Answer 71

and the x is negative then the formal will be
y-6 = 2(x+6)

Answer 72

ask any question dont hesitate

Answer 73

y – 6 = (2-6)/(-8-(-6))(x –(-6) )

Answer 74

it was y-6=2(x-(-6))

Answer 75

did not notice the 'negative' in the question

Answer 76

yes this right answer

Answer 77

yeah i found that out after i submitted it....

Answer 78

i kept getting confused because you put x+6 so i didnt add the negative..

Answer 79

you know now the answer ?

Answer 80

yes

Answer 81

y= 2x+18

Answer 82

this same function above after moving sides

Answer 83

you can check it with any point in the picture
