Answer:
The answer to this question is -3/6 is the slope
Step-by-step explanation:
First, you have to get the y its self to do that you have to subtract or minus -3x to the other side
3x+6y=12
-3x -3x
6y = -3x + 12 Divided by 6 to get y itself
6y/6=-3/6+12/6
y= -3/6x +3
and -3/6 is slope because it is in X
