Question

Find the slope of the line shown on the graph.

Have the picture of the graph attached to a response.

Answer 1

slope of the line right??

Answer 2

Yes, I need to find it.

Answer 3

okay slope is raise/ run and that is delta x / delta y do you recall this

Answer 4

Yes, but forgot how to do it.

Answer 5

so therefor it's slope= delta x/delta y (y1-y2) /(x1-x2) does this help?

Answer 6

So, I look to see what each point is?

Answer 7

yes

Answer 8

recall that on the x y graph y1 and x1 must the on that line it doesn't matter which is y1 or x1 it just matters it's X and Y and than plug in and solve

Answer 9

Ok, so the graph shows the first point is on the y axis 2. So it would be (0,2) and the other is (5,0)?

Answer 10

right so use the formula I just gave you, in this case I am sorry it will matter which is 1for y and x in this problem.

Answer 11

So far I got \[2 \over 5 \]

Answer 12

that is the slope of that line

Answer 13

So - \[2 \over 5\]

Answer 14

Thanks. :)

Answer 15

do you mean -2/5?

Answer 16

Yeah, don't know why it went like that.

Answer 17

hint look at which the line is angled on the graph if it is right to left most likely + if the line goes from left to right angle it is negative

Answer 18

another clue where does the line cross the y at if it's at - than it is negative

Answer 19

make sense??

Answer 20

meant to say x not y

Answer 21

Yeah, now just to figure this next one out, one of the y's is negative and the other is positive and both x's are positive.

Answer 22

what is the problem asking for??

Answer 23

SLope again lol. (4,0) and (0,-5)

Answer 24

yes

Answer 25

does it anything like MX+B point slop form? just checking.

Answer 26

Just asks to find to slope if it exists of the line.

Answer 27

okay than..

Answer 28

If i am doing this right, there is no slope.

Answer 29

correct

Answer 30

or we say undefined

Answer 31

because if you divide by 0 it is undefined

Answer 32

ex 0/2 that would be undefined

Answer 33

Alright. And I hate when it does these problems in a row. now it is (2,-9) and (-2,-9) Which is: \[0 \over -4\]

Answer 34

ask yourself can divide 0/-4 if the answer is no than it is undefined

Answer 35

also keep in this mind when doing these, ******** the first number is always always X and the second number is always Y DON"T REVERSE THEM!!! :)

Answer 36

0/-4 would be 0 if I do that correctly.
I always get the division mixed up for some reason.

Answer 37

let us back up for one min here, if I gave (1,-5) and (9,0) which number is the x and Y?

Answer 38

Y is -5 and 0. X is 1 and 9.

Answer 39

that is how you enter them into the slope formula.

Answer 40

so the one would X1 and the -5 would be Y1
