see below...

Explanation:

we make a table of values.

#x=-5#

in the equation #y=-(-5)-1# we get #y=4#

#x=5#

in the equation #y=-(5)-1# we get #y=-6#

plot them on graph and we get a straight line

graph{-x-1 [-10, 10, -5, 5]}

you can keep putting values in the equation to make a bigger graph.
