Answer:
-1
Explanation:
Before finding the slope of the line, we have to rewrite its equation in the slope-intercept form, so in the form
y=mx+q(1)
Here the equation of the line is.
6x+6y+11=0
By manipulating the equation we find:
-6x-11=6y
y=-

y=-x-11/6
So, the equation of the line in the slope-intercept form is
y=-x-11/6
And by comparing it with (1), we find:
m=-1
q=-11/6
So, the slope is -1, and the y-intercept is -11/6.
