This is not a direct variation equation. ($y$ does not vary directly with $x$).
Work Step by Step
We can isolate y by subtracting 3 from both sides. We have $y=-3x-3$. Direct variation can be represented as $y=kx$, where k is the constant of variation. This equation cannot be represented as $y=kx$ because it has a y-intercept, so this is not a direct variation equation.
