See Below.

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

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

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

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

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

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

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

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

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

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

graph{-3x-1 [-10, 10, -5, 5]}
