Question

Write the equation y - 2 = 2(x - 3) in standard form.
Answer

y - 2x = 4

2x - y = -6

2x + y = 6

2x - y = 4

Answer 1

@hba by standard form do they mean y=mx+b?

Answer 2

Standard form is,

\[\huge\ Ax+By+C=0\]

Answer 3

Where C is the constant :)

Answer 4

?

Answer 5

Um arrange it in this order.

1) expand x terms out and get all of them on Left hand side

Answer 6

yeah im comply lost dude

Answer 7

Where are you confused ?

Answer 8

the whole thing like as soon as ya put up the standard form it lost me cuz where r we getting the a b and c?

Answer 9

so y-2=2x-6?

Answer 10

Let me show you an example

6x+5y-6=0

^ like this

So its standard form we write Ax+By+C=0

Answer 11

y-2=2x-6

Add 6 on both sides :)

Answer 12

y-8=2x?

Answer 13

-2+6=

Answer 14

oh 4
so y+4=2x?

Answer 15

Now subtract

(y+4) from both sides :)

Answer 16

wait how do i do that if their is only 2x?

Answer 17

(y+4)-(y+4)=2x-(y+4)

Answer 18

???? so it would give me 2x-y+4

Answer 19

0=2x-y-4

or

2x-y-4=0

^ Answer

Answer 20

none of my answers at the top match that though

Answer 21

@hba

Answer 22

Add both sides by 4 then :)

Answer 23

oh so it would be 2x-y=4

Answer 24

here are various forms of the equation of a line
