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

Explanation:

#y=-x-2#
we can try #x# from #-1# to #1# and workout y possibilities.

#x=0#
#y=0-2=-2#

#x=1#
#y=-1-2=-3#

#x=2#
#y=-2-2=-4#

#x=-1#
#y=-(-1)-2=1-2=-1#

#x=-2#
#y=-(-2)-2=2-2=0#

plot the coordinates# (0,-2),(1,-3),(2,-4),(-1,-1)# and# (-2,0)# and match them to get a straight line.
