Let's solve the inequality:
[tex]\begin{gathered} 6y<48 \\ y<\frac{48}{6} \\ y<8 \end{gathered}[/tex]Once we have the solution we can graph it on the line, to do this we draw a number line and draw a circle above 8; finally we draw a line to the left (since the variable is less than y). Therefore, the graph of the inequality is:
The solution in interval notation is:
[tex](-\infty,8)[/tex]
