Answer 2

@Luigi0210

Answer 3

@Nnesha

Answer 4

it wont let me open the document for some reason...

Answer 5

Better??

Answer 6

so you need to figure out what exactly? like a percentage, or rate?

Answer 7

Like the I need to find the equation in point-slope form

Answer 8

@pooja195

Answer 9

rose are you going to help or can i start ?? :=))

Answer 10

You can start if you want

Answer 11

rose came here first don't want to jump in :=))

Answer 12

so i don't **

Answer 13

Oh yeah that's true

Answer 14

no its ok you can start

Answer 15

anywz y=mx+b is a slope intercept form
where m is slope and b is y-intercept
`y-intercept` is a point where line intersect the y-axis
in other words starting amount(time ) represent y-intercept

Answer 16

what would be the y-intercept ?

Answer 17

(0,300) so 300

Answer 18

perfect
now pick two points on the line to find slope

Answer 19

two points should (x,y)(x,y) two order pair :=))

Answer 20

(450,0) and (0,300) ???

Answer 21

Then I think the slope is -2/3

Answer 22

nice \[\huge\rm \frac{ y_2 -y_1 }{ x_2 -x_1 }\] formula to find slope plug in x and y values

Answer 23

-2/3

Answer 24

nice that's right :=))

Answer 25

you need `point slope ` form right ?

Answer 26

yes

Answer 27

I don't know what to put for y1 and x1

Answer 28

\[\huge\rm y -y_1 =m(x-x_1)\] m is slope

Answer 29

you can put any put that is `on the line `

Answer 30

(450,0) and (0,300)
doesn't matter which one u pick

Answer 31

ohhh okay so y- 450= -2/3( x- 0)

Answer 32

wait no

Answer 33

y- 0= -2/3( x- 450)

Answer 34

right :=))

Answer 35

That's all right?

Answer 36

yes right good job :=)) keep it up!! :=)

Answer 37

Thank you so much you're a life saver
