Transpose 9x to the right side of the equation: 3y = -9x - 81.
Divide both sides by 3: y = -3x - 27.
This is already in slope-intercept form: slope is -3, while y-intercept is -27.

The first step to find slope is always to get y by itself. Once you have an equation in slope-intercept form, the coefficient of x is the slope.
9x + 3y = -81
First, subtract 9x from both sides.
3y = -9x - 81
Next, divide EVERYTHING by 3 to finish getting y by itself:

y = -3x - 27
The slope is the number attached to x: -3
