Slope: #-1#
#y#-intercept: #-2#.

Explanation:

To find the slope and the #y#-intercept of a line, you need to put it in the form

#y=mx+q#.

Then, #m# will be the slope and #q# the intercept.

In your case, it is very simple, because you only need to isolate the #y#, bringing the term #x+2# on the right hand, and thus changing its sign into #-x-2#. Once in the form #y=-x-2#, you'll have #m=-1# and #q=-2#.
