It's - 6/7. You have to first change this into slope intercept form so you want the y by it self
It'll turn into
-7y=3x+6
You then have to divide everything by - 7
y=-3/7x - 6/7
Since the y intercept is b in mx+b - 6/7 is your answer

The y-intercept is located at (0, - 6/7)
Step-by-step explanation:
First, we should convert this equation from Standard Form (ax+by+c=0) into Slope-Intercept Form (y = mx+b), with b being the y-value of the y-intercept.
Work:
3x+7y+6=0
First, isolate the variables by subtracting 6 from both sides to keep the equation equal
3x+7y = - 6
Next, isolate the y-variable by subtracting 3x from both sides to keep the equation equal
7y = - 3x - 6
Then, divide by + 7 on both sides to keep the equation equal and to simplify the left side even more, to completely isolate the variable
y = - 3x/7 - 6/7
The y-intercept is located at (0, - 6/7)
