$- 2 x = y - 3$

Step 1

Rewrite the equation as $y - 3 = - 2 x$ .

$y - 3 = - 2 x$

Step 2

Add $3$ to both sides of the equation.

$y = - 2 x + 3$

Step 3

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
