    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)
