The problem is to solve the inequality $2r \le 8$ and graph the solution.

1. Problem Description

The problem is to solve the inequality $2r \le 8$ and graph the solution.

2. Solution Steps

To solve the inequality $2r \le 8$, we need to isolate $r$. We can do this by dividing both sides of the inequality by

2.

$2r \le 8$

$\frac{2r}{2} \le \frac{8}{2}$

$r \le 4$

The solution to the inequality is $r \le 4$.

To graph the solution on a number line, we need a closed circle at 4, since $r$ can be equal to 4, and an arrow pointing to the left, representing all values less than

4.

3. Final Answer

$r \le 4$
