A: y+4=8/5(x+3)
B: -8x+5y=17
C: y=8/5x+17/5
D: 5x-8y=17
I think its just A but its a multiple choice question so im not sure if there is another one...

Answer 1

wait a minute

Answer 2

Well first things first:

the graph starts at y = 3
slope is 3/2
so the equation would be
y=3/2x+3

Now just solve for the equation so that it looks like the one above.

Answer 3

I think the slope is 8/5

Answer 4

I dont have time... Uhhh... i got the equation but how to solve it?

Answer 5

y+4=8/5(x+3) is the equation i get

Answer 6

Which is also A...

Answer 7

And the slope is definately 8/5, because it moves 8 up and 5 to the right

Answer 8

It should be 8/5x + 17/5

Answer 9

I dont know if there is more answers than one...

Answer 10

Yes there is

Answer 11

Wait what why? How?

Answer 12

-8x + 5y =17 also works, there the same equation in different forms

Answer 13

Hmn... I get that one...

Answer 14

Do you get what im saying

Answer 15

Yeah... I just ran into a bit of trouble for a second @.@

Answer 16

isolate y from -8x + 5y =17

Answer 17

LET ME JUST SAY

Answer 18

the y intercept is 3.4

Answer 19

Yeah i remember, i learned to use slope to find a point on the grid.

Answer 20

so in mx + b the b is 17/5

Answer 21

quick quick which equations makes the b 17/5

Answer 22

Then pop it in to y-y1=m(x-x1)

Answer 23

that works i guess

Answer 24

slope point form also works

Answer 25

shawn! how are you doing?

Answer 26

Woah intense connection problems

Answer 27

You're right sorry thought it was directly on y=3 but it was just above it.

Answer 28

K back its still running slow, but i forgot what B was for again...

Answer 29

I have it written down somewhere...

Answer 30

the B is the y intercept and we know what that is!

Answer 31

Ohh

Answer 32

17/5 is the y intercept

Answer 33

(Whats a y intercept ._.) JK

Answer 34

Yeah i see c:

Answer 35

so in A B C D where do you see (or can make) 17/5

Answer 36

C?

Answer 37

yes! but there is one more! don't be fooled

Answer 38

I think its D.

Answer 39

no!

Answer 40

\[B: -8x+\color{red}5y=\color{red}{17}\]

Answer 41

Oh i thought we werent counting A and B because we already knew those were correct.

Answer 42

if i change B i get
\[B: \color{red}5y=\color{red}{17}+8x\]
\[B: y=\frac{ \color{red}{17} }{ \color{red}5 }+\frac{ 8x }{ 5 }\]

Answer 43

A is incorrect

Answer 44

Wha? ._.

Answer 45

wait let me recheck!

Answer 46

Its follows y+y1=m(x+x1) perfectly...

Answer 47

okay A is definately incorrect

Answer 48

Why...

Answer 49

let me put it into your form and take a look at it

Answer 50

y-y1=m(x-x1) Replace them to...
y-4=8/5(x-3) Swap the -'s for +'s because the numbers were negative...
y+4=8/5(x+3) And that answer is A...

Answer 51

XD are you sure that when you made the graph into y-y1=m(x-x1)
Did you switch the x and y?

Answer 52

you did, you switched the x and y

Answer 53

*facepalm*

Answer 54

LOL

Answer 55

Thats the first time i ever messed that up ._.

Answer 56

Hah, thanks for telling me O_O

Answer 57

its okay, for the longest time I kept messing up on my math tests

Answer 58

every single time i missed a negative somewhere

Answer 59

I mess up one of the multiple choices, i get an instant 0 points

Answer 60

No matter if i got another one of the answers right

Answer 61

hold on for one minute. ask questions if you need to

Answer 62

I think thats it.

Answer 63

good! hope you do well

Answer 64

It was rite yae

Answer 65

I'm guessing you go to k-12 correct? Because I do too xD
