Answer:
-2 is the slope
Explanation:
To find the slope of the line, we need to solve for y
6x +3y = 12
Subtract 6x from each side
6x-6x +3y = -6x+12
3y = -6x+12
Divide each side by 3
3y/3 = -6x/3 +12/3
y = -2x+4
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
-2 is the slope and 4 is the y intercept
