draw a line with a slope of 1/4 through the point (0,-4)

OpenStudy (kidrah69):

y=mx+b

OpenStudy (kidrah69):

m=slope b= -4

OpenStudy (pinklion23):

okay what is the question

OpenStudy (kidrah69):

Wrong

OpenStudy (kidrah69):

+- dont make sense

OpenStudy (kidrah69):

you have a negative 4

OpenStudy (kidrah69):

so there is not need for +

OpenStudy (anonymous):

OpenStudy (anonymous):

one of them is the answer

OpenStudy (ashes.boom):

slope is the change from one point to another so starting with the point you have move one point over and four points up

OpenStudy (ashes.boom):

does taht make sense?

OpenStudy (anonymous):

not really

OpenStudy (ashes.boom):

okay so the slope is 1 over 4. The slope represents the distance from the starting point to the new point you want to make okay?

OpenStudy (ashes.boom):

so starting at 0, -4 you move one to the right (becuase the slope is positive) getting you to 1, -4. you following?

OpenStudy (ashes.boom):

then you use the 4 from the slope to move 4 up (again because the slope is positive) getting you to (1, 0)

OpenStudy (ashes.boom):

make sense?

OpenStudy (anonymous):

let me try

OpenStudy (ashes.boom):

okay

OpenStudy (anonymous):

all this on a graph

OpenStudy (ashes.boom):

tag me when your done okay

OpenStudy (anonymous):

i dont get it at all @Ashes.boom

OpenStudy (ashes.boom):

okay lets take a look at the last graph alright?

OpenStudy (anonymous):

ok

OpenStudy (ashes.boom):

what is the starting point

OpenStudy (anonymous):

-4

OpenStudy (ashes.boom):

(0, -4) the zero is important, it tells you that the point is on the x axis, does that make sense

OpenStudy (anonymous):

yes

OpenStudy (ashes.boom):

okay so you know that (x, y) are coordinates so your x value is 0 and the y is -4.

OpenStudy (anonymous):

yes

OpenStudy (ashes.boom):

how do you get from 0, -4 to 1, -4?

OpenStudy (anonymous):

moving one

OpenStudy (ashes.boom):

in what direction?

OpenStudy (anonymous):

right

OpenStudy (ashes.boom):

yes perfect. because you moved right, you "added" 1 does that make sense

OpenStudy (anonymous):

yeah

OpenStudy (ashes.boom):

okay so the top part of your slope is what?

OpenStudy (anonymous):

-1

OpenStudy (ashes.boom):

positive 1

OpenStudy (anonymous):

0

OpenStudy (ashes.boom):

if it was negative one you would have moved to the left into the negative numbers

OpenStudy (anonymous):

right

OpenStudy (ashes.boom):

so the first part of your slope is 1, right?

OpenStudy (ashes.boom):

Now, how do you get from 1, -4 to 1, -3?

OpenStudy (ashes.boom):

same way you moved the x value...

OpenStudy (anonymous):

whats the answeer

OpenStudy (ashes.boom):

its the last graph

OpenStudy (anonymous):

i knew it

OpenStudy (ashes.boom):

when you look at it can you see how you move over 1 and up 4?

OpenStudy (anonymous):

thats crazy

OpenStudy (anonymous):

yeah

OpenStudy (ashes.boom):

okay cool! i hope that helped a little

OpenStudy (anonymous):

yeah thx

OpenStudy (ashes.boom):

your welcome :)
