Question

What is y=2x-3 in standard form?

Answer 1

`2x + y =-3`

Explanation:

Standard Form for writing down a Linear Equation is:

`color(red)"A"` `x` + `color(blue)"B"` `y` = `color(green)"C"`

• `color(red)"A"` shouldn't be negative,`color(red)"A"` and `color(blue)"B"` shouldn't both be zero, and `color(red)"A"`, `color(blue)"B"` and `color(green)"C"` should be integers.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

`y=2x-3` to standard form:

Bring 2x to the left side

-2x-y=3

Multiply all by -1

I`color(darkred)"Remember!"`
I
I`color(red)"A"` `color(darkblue)"mustn't be negative"`

`2x + y =-3`

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Note:
`color(red)"A"` `=2`
`color(blue)"B"` `=1`
`color(green)"C"` `=-3`
