How do you find the slope of #y=-9/4x-2#?
The equation is already in the slope-intercept form:
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.
Differentiating both sides wrt x, we get,
which is the required slope.
