Question

How to find the coordinates for finding the slope? I'm having trouble with figuring out how to read the graphs to find the coordinates. Could anyone help me? Posting attachment below.

Answer 1

I have to find the slope but am having trouble.

Answer 2

@e.mccormick

Answer 3

See those 3 dots? Well pick one.

Answer 4

Any of them?

Answer 5

Uh Huh

Answer 6

Okay I guess the second one going down then. at the 2.

Answer 7

2 of them srry

Answer 8

Pick 2

Answer 9

Okay.. and the top one.

Answer 10

So the top and the middle?

Answer 11

yeah

Answer 12

\[m=\frac{ -2 }{ 1 }\]

Answer 13

For Y=mx+b

Answer 14

?

Answer 15

Fo just -2

Answer 16

We have to make an equation

Answer 17

so now we have y=-2x=b Now we will find b (y-intercept)

Answer 18

I thought you just had to find the coordinates and then put them in a fraction and subtract :/

Answer 19

I did that part for you

Answer 20

? What are the coordinates?

Answer 21

Top and the middle

Answer 22

like how-- they have to be like.. (2, _ ) and that kind of thing

Answer 23

@dan815 IDK what she is talking about

Answer 24

I'm telling you how to find the equation of the line

Answer 25

Like okay so to find it you have to get the coordinates for example
(3, 4) (1, 3) then you put them together like
3 - 1
_____
4 - 3 and then it'd be
2
_
1 and that'd be the slope for example/

Answer 26

You should read this. It will help. http://openstudy.com/updates/5533407ce4b021d09bb190df

Answer 28

I just need to find the slopeeee

Answer 29

the points are labelled in the form (x,y)

Answer 30

Slope =M And M=-2

Answer 31

Ill show you.

Answer 32

Oh. All I had to do was find the slope :/

Answer 33

sam, you got the slope equation backwards

Answer 34

it is the change in y/ change in x
so
"Like okay so to find it you have to get the coordinates for example
(3, 4) (1, 3) then you put them together like
4-3 <-------- like this
_____
3-1 and then it'd be
2
_
1 and that'd be the slope for example/"

Answer 35

Slope=Rise/Run, the change in vertical distance/ change in horizontal distance

Answer 36

\[M=\frac{ y2-y1 }{ x2-x1 }\]

Answer 37

Yeah my bad haha

Answer 38

Yes yes I was having trouble finding the x and y coordinates

Answer 39

Those are the points on the line

Answer 40

The 3 dots You just have to pick 2 of then

Answer 41

I know but I don't know how to read them

Answer 42

Ohhh Ill show u

Answer 43

that was my question lolol sorry :P

Answer 44

http://prntscr.com/6xdpj1 Go up nd over

Answer 45

(-1,4)

Answer 46

ooooh

Answer 47

So you do the middle point

Answer 48

( 0, 2)?

Answer 49

YES!!! Do the last 1 now.

Answer 50

(2, -2)?

Answer 51

NOOOO

Answer 52

O_O

Answer 53

Answer 54

(1,2)

Answer 55
