See Below.

Graphing "using a table" just means choose a few values for #x# and compute #y# to get some ordered pairs to graph.

It's good practice to choose a few negative values, a few positive values and zero for #x#.

#x=-3#,#y=8#,(-3,8)#

#x=-2#,#y=5#,(-2,5)#

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

#x=0#,#y=-1#,(0,-1)# This is the y-intercept.

#x=1#,#y=-4#,(1,-4)#

#x=2#,#y=-7#,(2,-7)#

#x=3#,#y=-10#,(3,10)#

Here's what the graph looks like after you've plotted the points above and connected them.
