Answer 1

The table below represents a linear function f(x) and the equation represents a function g(x):


x
f(x)
-1
-11
0
-1
1
9
g(x)

g(x) = 5x + 1



Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

Part B: Which function has a greater y-intercept? Justify your answer. (4 points)

Answer 2

x f(x)
-1 -11
0 -1
1 9

Answer 3

g(x) = 5x + 1

This is in the form of y = mx + b, where 'm' is the slope, so can you identify the slope of g(x) = 5x + 1?

Answer 4

is this for part a ? @iGreen

Answer 5

And to find the slope of f(x) use the formula
\(\sf\Large\frac{y_2-y_1}{x_2-x_1}\) where the points are \(\sf (x_1,y_1), (x_2,y_2)\)

Answer 6

And yes @hiopenstudy

Answer 7

ok @TheSmartOne

Answer 8

so which points do i use

Answer 9

you can use any 2, you want to. They will give you the same value regardless of which point you choose :)

Answer 10

do they have they have to be on the table ?

Answer 11

The 3 points they gave us, and you choose any 2 out of these

(-1,-11)
(0,-1)
(1,9)

Answer 12

lets do the first one

Answer 13

we only have a y1 and an x1 though :( what are we going to do

Answer 14

@TheSmartOne

Answer 15

PLEASE HELP Y MOM IS GOING TO YELL AT ME IF I DO NOT FINISH IN 10 MINUTES DO YOU NOT CARE

Answer 16

@TheSmartOne please help i am literally begging you and crying kind of i need help please please please do you not understand

Answer 17

@satellite73 @Abhisar

Answer 18

soemone help please

Answer 19

@sleepyjess @pooja195

Answer 20

@.Sam.

Answer 21

pick 2 points

Answer 22

-1,-11

Answer 23

@sleepyjess

Answer 24

that is one point, pick another

Answer 25

0,-1

Answer 26

Ok, now we just substitute those into the slope formula

Answer 27

ok may you do that @sleepyjess

Answer 28

you know the slope formula right?

Answer 29

yes

Answer 30

Y1-Y2/X2-X1

Answer 31

ok, just plug in the numbers, it isn't that tough

Answer 32

well what am i going to with y 2 an dx 2 just put them as 0

Answer 33

HURRY

Answer 34

1, -11 = \(x_1, y_1\)
0, -1 = \(x_2, y_2\)

Answer 35

0+11/0-1

Answer 36

how are you getting that?

Answer 37

what are you getting

Answer 38

the formula is \(\dfrac{y_2-y_1}{x_2-x_1}\). there is only one 0 involved

Answer 39

-1+11/0-1? @sleepyjess

Answer 40

yes

Answer 41

the answer to that so far is -10 @sleepyjess, so can we go on

Answer 42

yes

Answer 43

so can we right the sentence yet or not yet....

Answer 44

@sleepyjess

Answer 45

sentence?

Answer 46

look at what i have to do ?

Answer 47

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

Part B: Which function has a greater y-intercept? Justify your answer. (4 points)

Answer 48

ok, so what is the y-intercept of the other function?

Answer 49

which one ?

Answer 50

the g(x) one @sleepyjess

Answer 51

yes

Answer 52

@hiopenstudy come here :)

Answer 53

they are waiting 4 ur reply

Answer 54

i need help w. 2 questions at the same time is that possible i am so afraid my mom is giving 30 more minutes but she said i have to have my homework done and if not... you really do not want to know :(

Answer 55

@sleepyjess ok i am here

Answer 56

what is the slope of g(x)?

Answer 57

i have no clue may you help me find that :D

Answer 58

do you know what slope-intercept form is?

Answer 59

y=mx+b or. what you taught me

Answer 60

that is correct :)

Answer 61

so they gave us

g(x) = 5x + 1
and when the equation looks like y=mx+b the slope is m.

So what number is infront of x in:
\(\sf g(x) = 5x + 1\)

Answer 62

ok @TheSmartOne so can we hurry
