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

May 24, 2016

$2 x + y = - 3$

#### Explanation:

Standard Form for writing down a Linear Equation is:

$\textcolor{red}{\text{A}}$$x$ + $\textcolor{b l u e}{\text{B}}$$y$ = $\textcolor{g r e e n}{\text{C}}$

• $\textcolor{red}{\text{A}}$ shouldn't be negative,$\textcolor{red}{\text{A}}$ and $\textcolor{b l u e}{\text{B}}$ shouldn't both be zero, and $\textcolor{red}{\text{A}}$, $\textcolor{b l u e}{\text{B}}$ and $\textcolor{g r e e n}{\text{C}}$ should be integers.

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

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

Bring 2x to the left side

-2x-y=3

Multiply all by -1

I
I$\textcolor{red}{\text{A}}$ $\textcolor{\mathrm{da} r k b l u e}{\text{mustn't be negative}}$

$2 x + y = - 3$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Note:
$\textcolor{red}{\text{A}}$$= 2$
$\textcolor{b l u e}{\text{B}}$$= 1$
$\textcolor{g r e e n}{\text{C}}$$= - 3$
