Solve the given inequality for y:
[tex]\begin{gathered} x+y<-5 \\ y<-x-5 \end{gathered}[/tex]
Graph the borderline of the inequality, which is y=-x-5.
Since the sign of the inequality is less than, we have to change the continuous line for a dotted line and shade the region that is under the line, this way:
That is the graph of the solution set.
