Answer
$s\lt2$
Work Step by Step
$5s-3+1\lt8\longrightarrow$ combine like terms
$5s-2\lt8\longrightarrow$ add 2 to each side
$5s-2+2\lt8+2\longrightarrow$ add
$5s\lt10\longrightarrow$ divide each side by 5
$5s\div 5\lt10\div5\longrightarrow$ divide
$s\lt2$
The endpoint of the graph will be an open circle since 2 is not included in the solution set.
