# How do you write y - 2 = 4(x + 5) in standard form?

May 28, 2015

Standard form for a linear equation is (normally)
$A x + B y = C$ with $A \ge 0 \mathmr{and} A \epsilon \mathbb{Z}$

Given $y - 2 = 4 \left(x + 5\right)$

we can re-write:
$y - 2 = 4 x - 20$

$- 4 x + y = - 18$

$4 x - y = 18$ (standard form)
