Answer 2

Can you identify the y-intercept and the slope from the graph?
@pickachu123

Answer 3

Since the graph is negative, you can rule out two answers (C and D)
Then you look at the y-intercept (where the graph crosses on the y-axis) and you have your answer. Can you figure out the answer from that?

Answer 4

ok one sec

Answer 5

is it A

Answer 6

@mathmate not really

Answer 7

no it is not a cause that has a positive slope but the line is negative

Answer 8

No, because the graph crosses the y-axis at a negative point, not a positive point. So it would have to be negative 1, not positive one. Do you see what I mean?

Answer 9

oh I thought the line was positive well then it must be B

Answer 10

@pickachu123
If you can identify the slope and y-intercept, this kind of problem will be easy to solve.

Answer 11

the y intercept is -1 and the slope is -2

Answer 12

The y-intercept is where the graph cuts the y-axis, and in the equation, this number equals the value of y when x=0.

Answer 13

ok

Answer 14

So look up the equations y=mx+b
m=-2, and b=-1

Answer 15

...and then make your choice!

Answer 16

I have another question one sec

Answer 17

What did you get for this one?

Answer 18

* get -> choose

Answer 19

Which equation represents the graph of the linear function?

A. y = −4x + 4

B. y = −4x − 4

C. y = 4x + 4

D. y = 4x − 4

Answer 20

@mathmate its B

Answer 21

Yep, that's correct!

Answer 22

ok thank you

Answer 23

Now, for this one, what is the slope and y-intercept?

Answer 24

slope is 4 and x is -4 I think

Answer 25

y-intercept is the value of y after putting x=0!

Answer 26

Also check the graph, where does the line cut the y-axis?

Answer 27

umm I don't have to simplify the questions just wants to no which one is the rise over run for the graph

Answer 28

Rise is vertical, run is horizontal. (but your slope is correct).

Answer 29

ok whats the x I don't know what that one is

Answer 30

To find the equation, you don't need x.
y=mx+b
m is the slope (you found 4).
b is the y-intercept, the y-coordinate where the line cuts the y-axis, you can read from the graph.

Answer 31

@pickachu123
Still there?

Answer 32

yes @mathmate I lost connection

Answer 33

the answer is c @mathmate

Answer 34

The answer choice is secondary, I would like to see what you got for slope and y-intercept!

Answer 35

the slope is 4

Answer 36

and the y-intercept?

Answer 37

4

Answer 38

Perfect, so (c) is correct!

Answer 39

thanks @mathmate

Answer 40

You're welcome! :)

Answer 41

ok don't be mad I have another question :)

Answer 42

Complete the equation of the graphed linear function. Write the slope in decimal form.

y = ?x + ?

Answer 43

what is the y intercept of the graph

Answer 44

@mathmate @pizza12 can I have some help on this question

Answer 45

thanks @pizza12 I have one more question

Answer 46

Complete the equation of the graphed linear function in point-slope form.

y - (-2) = ? (x - ?)

Answer 49

its the last question

Answer 50

@pickachu123
People don't usually dig into an old question.
If you post a new question, it will be visible to more people who are already online, and you will get more help faster!

For this one, you again will find the slope and the intercept.
However, the intercept cannot be read off directly, so you can use the slope to help you find the intercept.

Answer 51

@mathmate ok and thanks for the help im done with my test
