Answer 1

Do you just need help with #3?

Answer 2

You would just need to replace y with f(x) then say that the function depicts an output for each input of x.

Answer 3

Your equation in slope intercept form is missing the x btw.

Answer 4

with -2/3? -2/3x?

Answer 5

yea only help with 3

Answer 6

\[y = -\frac{ 2 }{ 3 } + 490\]
\[y = 489 \frac{ 1 }{ 3 }\]

Answer 7

Yes you need the x

Answer 8

ok its that 3? ^

Answer 9

No. I was illustrating why your equation in #1 is incorrect. Without the x, it would be simplified to a straight line crossing the y axis at a perpendicular angle at y = 489 1/3

Answer 10

oh okie

Answer 11

does this look btr thn?

Answer 12

What is 'this'

Answer 13

Oh

Answer 14

lmao give me a sec to put the pic there XD

Answer 15

Yes, correct

Answer 16

ok lol

Answer 17

now part 3. ty for that btw.

Answer 18

Do you know how to put it into function notation?

Answer 19

I explained it briefly earlier.

Answer 21

Yes. So in this case y or f(x) is the # of wraps and x is the # of sandwiches. Do you see what's happening with this function?

Answer 22

yea

Answer 23

Since the # of wraps is alone on the left side, we can say that this function gives the # of wrap specials sold given the # of sandwich specials sold

Answer 24

ok

Answer 25

is this all i else need? i cant rly think of anything else to put if there is anymore .-.

Answer 26

No

Answer 27

sry i forgot to put the pic there .-.

Answer 28

I guess that's technically correct ._.

Answer 29

ok, can u help me out with the next part? i was told it was wrong by someone else .-.

Answer 30

Answer 31

lol

Answer 32

actually, let me try to correct it with the new info and ok i will leave u be lol sry :) im not on christmas break just yet

Answer 33

I mean its np I can take a look. I am just being lazy.

Answer 34

oh okie lol give me a sec i just gotta take a screenshot

Answer 35

heres one :

Answer 36

the 1st is for a closer look .-.

Answer 37

It says to note the intercepts

Answer 38

In lines 2 and 3 on the left, just write the coordinates. A dot should appear.

Answer 39

I believe there is an option to label those coordinates as well.

Answer 40

That is the x and y intercepts.

Answer 41

so then it would be (-2/3,490)?

Answer 42

what

Answer 43

How'd you get that

Answer 44

bc the equation is y = -2/3x + 490 .-. and 2/3x has 'x' in it so i thought it would be the x coordinate, and since 490 is the only other number in there i thought it may be the y coordinate

Answer 45

-2/3 is as you said earlier, the slope.

Answer 46

It is not a coordinate nor part of one.

Answer 47

An intercept is the point in which a line crosses an axis, either the x or y one.

Answer 48

Those are intercepts, because they 'crossed' the y axis and the x axis

Answer 49

Those are the intercepts.

Answer 50

Because they 'crossed' the y and x axis.

Answer 51

The y intercept should have some value for y, and x should always be zero, as it is right on the y axis. For the x intercept, y should always be zero with some value for x, as it is on the 'ground' floor.

Answer 52

uh

Answer 53

nvm hold on i didnt read what u just said

Answer 54

oh, okie, then it would be (0,490) on the y-intercept, right? .-.

Answer 55

does this look correct..?

Answer 56

Yes

Answer 57

ok ty
