Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts?
f(x) = x + 4
x g(x)
−1 8
1 0
2 −4
The function f(x) has a higher y-intercept.
The function g(x) has a higher y-intercept.
They both have the same y-intercept.
The relationship between y-intercepts cannot be determined.

- Nnesha

g(x) is same as y so first of all find y-intercept of de table

- Nnesha

y=mx+b is a slope intercept form
where m is slope and b is y-intercept
f(x)=x+4 <----what is the y-intercept in this equation ?

4

- Nnesha

yes right and what's the y-intercept of table ?

- Nnesha

the*

- anonymous

there is 0, 8, and -4

- anonymous

brb please i have to go help my mom out

- Nnesha

nope 0 ,8 and -4 are y values not y-intercept
first of all you have to find slope of the table and then y-intercept

- Nnesha

alright :-)

- anonymous

i meant \[\frac{ 8 }{ 2 } = \frac{ 4 }{ 1 }\\= 4\]

- Nnesha

formula is \[\huge\rm \frac{ y_2 - y_1 }{ x_2 - x_1 }\]plug in x and y values
u forgot something .-.

- anonymous

\[0 - 8 = -8 and 1 - (-1) = 2\] so we got -4 because \[- \frac{ 8 }{ 2 } = -4\]

- Nnesha

yes right

- anonymous

now what?

- Nnesha

now y = mx + b replace m by -4 plug in x and y values solve for b

- anonymous

okay so y = -4x +b
8 = -4(-1) + b
8 = 4 + b
-4 - 4
4 = b
b = 4

- Nnesha

yes right that's the y-=intercept of the table

- anonymous

so its C because they both have the same y-intercept

- Nnesha

yep right

- anonymous

can you help me with more because your so good at getting me to understand it and doing it myself :)

- anonymous

ill post them in a new thread so you can get more medals

- Nnesha

i'll try
and u can post here :-)

Alton has been recording the number of apples on his apple tree each week:
Week Apples
2 15
3 22
4 29
5 36
The function representing Alton's apples per week is f(w) = 7w + 1. What does the 1 represent?
The number of apples at the start
The week number when Alton recorded the apples
The number of apples Alton had in total
The number the apples increased by each week

- Nnesha

any idea ?

- anonymous

let me read it again

- Nnesha

alright

- anonymous

the y - intercept right because you said b = y-intercept or it means y intercept

- Nnesha

yep one is the y-intercept
so what would be ur answer ?

- anonymous

the numbers of apples at the start

- Nnesha

yes right bec when u substitute 0 for w
f(0)=7(0) + 1 you will get one
so y-intercept is also the starting point

- anonymous

okay thnx i have a coup[le more

- Nnesha

okay

- anonymous

Im gonna try to solve the next one on my own and you tell me if its right or wrong but this is the question

On the graph of the equation 8x − 3y = 24, what is the value of the y-intercept?
−8
8
−3
3

- anonymous

8x - 3y = 24
-8x - 8x
-3y = -8x + 24
/-3 /-3
y = -8x -8
so is the y - intercept -8

- Nnesha

alright that's right y-intercept is -8
but slope is not -8
divide both side by -3\[\frac{ -3y }{ -3} = \frac{ -8x+24 }{ -3 } = \frac{ -8x }{ -3 } +\frac{ 24 }{ -3}\]

- Nnesha

-8x+24 OVER -3

- anonymous

oh okay so its like this \[\frac{ -8x + 24 }{ -3 }\]

- Nnesha

yes right
-8x is dividing by -3 and 24/-3

- anonymous

okay but is the answer -8?

- anonymous

for the y-intercept?

- Nnesha

so how would you write equation in slope yintercept form ?

- anonymous

\[y = \frac{ -8 }{ 3 }x - 8\]

- Nnesha

yes right!

- anonymous

yay

- anonymous

Based on the table of values below, find the slope between points where x = 3 and where x = 7.
x y
3 1
4 6
7 9
−4
\[\frac{ 1 }{ 4 }\]
1
2 <--- my choice

- Nnesha

how did you get -4 and 1/4 ?

- Nnesha

ohh wait those are the choices alright
how did you get 2 ?

- anonymous

-4 , 1/4, 1, 2 are my answer choices

- anonymous

so i did \[\frac{ 9 - 1}{ 7-3 } = \frac{ 8 }{ 4 }\] = 2

- Nnesha

yes right

- anonymous

okay lol good i thought i did it wrong lol

After 3 months of living at his new house, Tony had 4 birds. Four months later, Tony still had 4 birds. Which of the graphs below models Tony's bird population?
graph of line going through 4, 0 and 4, 8
graph of line going through 0, 4 and 7, 4 <- my choice
graph of line going through 1, 5 and 4, 8
graph of line going through 4, 0 and 7, 3

- anonymous

let me know if you want the picture of the graphs

- Nnesha

i have to go make a new post
and yes we need graph

- anonymous

okay
