Answer:

the slope is #-1/3#

Explanation:

there are two ways, solve for y or graph
Add 2x to both sides
#-6y=2x+12#
next divide by -6
#y=2/6 x- 2#
-2/6 reduces to #-1/3#

graph{-2x-6y=12 [-10, 10, -5, 5]}

down one over three down one over three to get from
the x-intercept to the y-intercept. 1/3 and since it's a negative slope, #-1/3#
