Question

put this : -x + 3y = -6 into a slope - intercept form.

Answer 1

y = mx + c

m = slope

c = y intercept

Answer 2

ik the form, but i don't know how to put it in the form.

Answer 3

... what is slope ?

Answer 4

rearrange the equation into "y=..."

then you can compare with the form

Answer 5

y = m ( -x ) + 3y ?

Answer 6

noooooo!!!!!



you have y in the equation already dont you ?


-x + 3y = -6
^

Answer 7

rearrange that to get y equal something

Answer 8

do you know how to rearrange?

Answer 9

nope. not really :S

Answer 10

okay,




i show you





if we have 15x+3y=27

we can put x in the other side so we can have y on it own side without x


we do this by doing the opposite to each side...
for example


+15x+3y=+27 yes?

so if we do -15x+15x+3y=+27-15x

you see what we do on one side we must on the other

the -15x and +15x cancel giving 0

so we are left with

3y=+27-15x



we can further simplify this by dividing by 3


giving us

y=9-5x

do you understand this?

Answer 11

yea... 80% got this :)

Answer 12

great,

what dont you understand? (20%)?

Answer 13

we do this by doing the opposite to each side...
for example


+15x+3y=+27 yes?

( that part )

Answer 14

okay, the plus and minus cancel out, i only put them there for you to understand,


what dont you understand about it?

Answer 15

ohhh ok nvm i got it.

Answer 16

Hello, @Rubie I just wanted to make sure the answer you got for your original problem was correct. Can you tell me what you ended up with? :)

Answer 17

y = ox + 16/3 ?

Answer 18

Okay, no. We have...

-x + 3y = -6

We need it to look like: y = mx + b
first

Answer 19

Can't we move our negative 'x' to the other side of the equal sign by adding it?

Answer 20

-x + 3y = -6
+x +x
------------
3y = x - 6

Answer 21

so 3y = -6 + -x ?

Answer 22

ohhh

Answer 23

When you move something to the other side the sign changes. So positive would turn negative and a negative would turn positive.

Answer 24

oooo

Answer 25

Just remember I put the 'x' first since it must be in y = mX+b

Answer 26

ahh

Answer 27

3y = x - 6

Now I need to solve for the y.
So I must divide by 3 on both sides everything gets divided by this 3

\[\frac{ 3y=x-6 }{ 3 }\]

Answer 28

\[y=\frac{ 1 }{ 3 }x-2\]

Answer 29

Do you understand? @Rubie

Answer 30

ohhh thanks for showing me step by step. I get a better visual abt it. thank you :)

Answer 31

can i ask a bit more to this ?

Answer 32

ok

Answer 33

:| can you identify and explain why ?
a) How will the line move Left to Right?
b) Steeper or Shallower than the Parent Function?

Answer 34

So basically how would I graph this....
