Given the equation y=x-1, we have the following values for x:
[tex]\begin{gathered} x=-2 \\ \Rightarrow y=-2-1=-3 \\ x=-1 \\ \Rightarrow y=-1-1=-2 \\ x=0 \\ \Rightarrow y=0-1=-1 \\ x=1 \\ \Rightarrow y=1-1=0 \\ x=2 \\ \Rightarrow y=2-1=1 \end{gathered}[/tex]
next, the table should look like this:
and the graph would look like this:
