Isolate the variable on one side of the inequality to find the solution. $-1\geq\frac{r}{3}\longrightarrow$ multiply each side by 3 $-1\times3\geq\frac{r}{3}\times3\longrightarrow$ multiply $-3\geq r$ -3 is the solution at the endpoint. Any other number that is less than -3 is also part of the solution set.
