y and x intercept

y=-4/3 or -1 1/3.
x=-8/3 or -2 2/3

3x+6y=-8
Our unknown friend certainly gave you the correct answer, this is a little explanation
--------------------------------------
when x=0
6y=-8
y=-4/3 this is the y intercept
--------------------------------
when y=0
3x=-8
x=-8/3 this is the x intercept
