Find the y-intercept and slope of the line.

y=-3-9x

The y-intercept of the line can be found by setting x=0 and solving for y:

y = -3 - 9(0)
y = -3

So the y-intercept is -3.

To find the slope of the line, we can rearrange the equation into slope-intercept form:

y = -9x - 3

Now we can see that the slope of the line is -9.
