Answer:
0
Explanation:
To find the slope of a line given two points I just like to line up the points and subtract and then finally put 2nd difference/1st difference like this:
(-3 ,2)
(6 ,2)
----------
-9 0
2nd/1st=0/-9=0
So the slope is 0
P.S. You can also see if you plot the points you get a horizontal line after connection... Slopes of horizontal lines are 0 since slope=rise/run and there is no rise (there is zero rise)
