# How do you write y = 3x + 8 in standard form?

May 2, 2016

$3 x - y = - 8$

#### Explanation:

General "standard form" for a linear equation is
$\textcolor{w h i t e}{\text{XXX}} A x + B y = C$ with $A \ge 0$

$y = 3 x + 8$

$\rightarrow - 3 x + y = 8$

$\rightarrow 3 x - y = - 8 \textcolor{w h i t e}{\text{XX}}$ (or$\textcolor{w h i t e}{\text{XX}} 3 x + \left(- 1\right) y = - 8$)

Note the given form is $\underline{\text{standard slope-intercept form}}$
