see graph

Work Step by Step

Substituting $ x=0 $ in the given equation, $ x-y=-5 ,$ results to \begin{array}{l}\require{cancel} x-y=-5 \\ 0-y=-5 \\ -y=-5 \\ y=5 .\end{array} Substituting $ y=0 $ in the given equation, $ x-y=-5 ,$ results to \begin{array}{l}\require{cancel} x-y=-5 \\ x-0=-5 \\ x=-5 .\end{array} Substituting $ x=1 $ in the given equation, $ x-y=-5 ,$ results to \begin{array}{l}\require{cancel} x-y=-5 \\ 1-y=-5 \\ -y=-5-1 \\ -y=-6 \\ y=6 .\end{array} The table below summarizes the results above. It is also used to graph the given equation.
