Question

give the slope of the line

Answer 1

...

Answer 2

whats the equation of the line?

Answer 3

y=3x+36

Answer 4

have you tried how to work this out?

Answer 5

well actually there is no work to it really

Answer 6

you put the equation in slope intercept form
y= mx+b

( it is already in slope intercept form)

Answer 7

m= the slope

Answer 8

thank you (:

Answer 9

(change of y)
y = ------------ x + b
(change of x)

Answer 10

:)

Answer 11

Koyi set aside $850 he earned over the summer to use for miscellaneous expenses while he is away at collage. He plans to use $20 each week.

Answer 12

A .) Give a possible point ( x, y ) which fits this situation

Answer 13

o

Answer 14

B) Write an equastion for a line which relates x and

Answer 15

y

Answer 16

give the slope of this line

Answer 17

0????

Answer 18

well you start out with how much

Answer 19

i dont know thats the problem

Answer 20

im trying to help you solve the problem...

so you start out with how much money?

Answer 21

$850

Answer 22

yup

that is going to be your y intercept "b"

Answer 23

i think thats what they call it

Answer 24

But its asking give a possible point of x,y which fits this situation

Answer 25

we will get there

well its going to be the variable "b" value

Answer 26

i dont know heheh

Answer 27

so you will use 20 dollars weekly right?

Answer 28

yeah

Answer 29

so what would that look like :)

Answer 30

i dont know you tell me (:

Answer 31

this is what we have so far

y=mx+850

Answer 32

what would a negative slope look like?

Answer 33

Kay then it asks write and equation for a line which relates x and y

Answer 34

going down

Answer 35

yes it is going down but how would it be written in slope intercept form (use any number, for example)

this is incomplete

y=mx+850

Answer 36

-850 (:

Answer 37

?????

Answer 38

hello ?

Answer 39

that is the y intercept
it tells you what at what point you start from

in our case in this problem presented

$850 you start from (0, 850)

now it will be decreased at a constant rate by 20 dollars (make a negative slope)

y= mx +b

b = y intercept
m = slope

how do you make a negative slope

Answer 40

- 850

Answer 41

im sorry i just dont get it

Answer 42

( change of y )
y= -------- x + b
(change of x )

Answer 43

does that help

Answer 44

still dont

Answer 45

if you want to make the line go down what do you use x value or y value?

Answer 46

the y value

Answer 47

good

so you start at 850

Answer 48

then you go down at a constant rate of what?

Answer 49

do i have to make the grid

Answer 50

umm from your questions that you asked

no

Answer 51

but do you know how to insert drawings here i just want make it easier to understand? :P

Answer 52

it goes down at a constant rate of 20

Answer 53

okay
