Write in Standard Form y-x+4=0

$y - x + 4 = 0$

The standard form of a linear equation is $A x + B y = C$ .

Rewrite the equation.

$0 = y - x + 4$

Move all terms containing variables to the left side of the equation.

Subtract $y$ from both sides of the equation.

$- y = - x + 4$

Add $x$ to both sides of the equation.

$- y + x = 4$

Reorder $- y$ and $x$ .

$x - y = 4$
