y=2-3x
Nnesha (nnesha):
do you need to graph that equation ?
OpenStudy (radvedder):
No I just need to put it in Standard Form
OpenStudy (radvedder):
Determine whether each equation is a linear equation. Write yes or no. If yes, write the equation in standard form.
Nnesha (nnesha):
oh alright
standard form is Ax+By =C

Yes but I don't know how to get it in standard form
Nnesha (nnesha):
just move the x term to the left side
OpenStudy (radvedder):
:( like -3x??
Nnesha (nnesha):
yes that's the x term so how would you cancel out -3x from right side ?
would you add ,subtract divide or multiply 3x?
OpenStudy (radvedder):
add 3x?

Nnesha (nnesha):
yes right do it! :=)
OpenStudy (radvedder):
but now it's 1y+3x=2 ??
Nnesha (nnesha):
yes
x comes first
so 3x+y =2
OpenStudy (radvedder):
And that's the answer?
OpenStudy (radvedder):
Can you help me with more of them please?

i'll try i'm here for few mints
OpenStudy (radvedder):
Ok and 5x=y-4
OpenStudy (radvedder):
add 4?
OpenStudy (radvedder):
or subtract 1y
Nnesha (nnesha):
you should move the y to the left side so subtract y

OpenStudy (radvedder):
and I got 5x-y=-4 correct?
Nnesha (nnesha):
looks good
OpenStudy (radvedder):
and on 5x+6=3x+2
I subtract 3x from each side and I get 2x+6y=2
?
Nnesha (nnesha):
is it 6y ? then yes
OpenStudy (radvedder):
Yes it is

OpenStudy (radvedder):
Ok and y=2x+5
Subtract 2x from each side
is it -2x+y=5?
OpenStudy (radvedder):
or 2x-y=5
Nnesha (nnesha):
i'll go with 2nd one
my teach taught us to multiply by negative one if a is negative
Nnesha (nnesha):
so both are the same
depends on options ....
