Answer
y-int: -18; x-int: 3
Work Step by Step
We know that $y=mx+b$, where m is the slope and b is the y-intercept. Using this, we find that the equation in slope intercept form is:
$$ 6x-y=18\\ y=-18+6x$$
Thus, the y intercept is $-18$.
Plugging in zero for y, it follows that the x intercept is:
$$ 6x-0=18 \\ x=3$$
