Find the vector and parametric equations for the line through the point $P=(-3, 1, -3)$ and parallel to the vector $\langle 3, 5, -3 \rangle$.

Vector Form: $\mathbf r = \langle$, , -3 $\rangle + t \langle$ , , -3 $\rangle$

Parametric form (parameter $t$, and passing through $P$ when $t = 0$):

$x = x(t) =$
$y = y(t) =$
$z = z(t) =$
