Chapter 2.2, Problem 8E

To determine

To graph:

The solution set for the following inequalities:

  $1\le s-8$

Explanation of Solution

Given information:

  $1\le s-8$

Graph:

  

Interpretation:

The given inequality equation is:

  $1\le s-8$

Need to switch sides:

  $s-8\ge 1$

Now add $8$ on the both sides of above equation:

  $\begin{array}{l}s-8\ge 1\\ s-8+8\ge 1+8\\ s\ge 9\end{array}$

So, the solution set of $s\ge 9$ is graphed as above.
