To locate the intercept using the $y$ axis, substitute $x=0$ into the equation of the line to find:

$y=-3\cdot 0-3=-3$

So the $y$ intercept is at $(0,-3)$

To locate the intercept using the $x$ axis, substitute $y=0$ into the equation of the line to find:

$0=-3x-3$

Add $3x$ to both sides to get:

$3x=-3$

By dividing both sides, $3$ to get:

$x=-1$

So the $x$ intercept is at $(-1,0)$
