Answer:

-9/4

Explanation:

The equation is already in the slope-intercept form:

#y = mx + c#
The coefficient of x is the slope, and the constant is the y-intercept. Equations in other forms can be converted to this form to calculate slope.

If you are looking for a better answer, you always find slope by differentiating.
For:
#y=-9/4x -2#
Differentiating both sides wrt x, we get,
#d/dx (y) = d/dx (-9/4x-2)#
Or, #dy/dx = -9/4#
which is the required slope.
