Question

solve the inequality and graph the solution.
-1 > \frac{s + 1}{3}
plot the endpoints. select an endpoint to change it from closed to open. select the middle of the segment, ray, or line to delete it.

Explanation:

Step1: Multiply both sides by 3

$3\times(-1)>\frac{s + 1}{3}\times3$
$-3>s + 1$

Step2: Subtract 1 from both sides

$-3-1>s+1 - 1$
$-4>s$ or $s<-4$

Answer:

The solution of the inequality is $s < - 4$. On the number - line, we use an open circle at $-4$ (because the inequality is strict, $s$ cannot equal $-4$) and draw a ray to the left of $-4$.
