we must evaluate the domain points in the function
[tex]y=60-8x[/tex]
x=0
[tex]\begin{gathered} y=60-8(0) \\ y=60 \end{gathered}[/tex]
x=1
[tex]\begin{gathered} y=60-8(1) \\ y=52 \end{gathered}[/tex]
x=2
[tex]y=44[/tex]
x=3
[tex]y=36[/tex]
x=4
[tex]y=28[/tex]
x=5
[tex]y=20[/tex]
x=6
[tex]y=12[/tex]
x=7
[tex]y=4[/tex]
the points are
[tex]\begin{gathered} (0,60) \\ (1,52) \\ (2,44) \\ (3,36) \\ (4,28) \\ (5,20) \\ (6,12) \\ (7,4) \end{gathered}[/tex]
now, locate each point on the graph and join with a line
