# What is y = 2x -4 in standard-form?

May 2, 2015

The answer is $- 2 x + y = - 4$ or $2 x - y = 4$ .

Standard form is $A x + A y = C$.

Convert $y = 2 x - 4$ to standard form.

Subtract $2 x$ from both sides.

$y - 2 x = - 4$

Place the $x$ term in front of the $y$ term.

$- 2 x + y = - 4$

You could also multiply the equation times $- 1$ (optional).

$2 x - y = 4$
