Answer

$y\geq2.5$

Work Step by Step

Find the solution by isolating the variable, y, on one side of the inequality. $y-1\geq1.5\longrightarrow$ add 1 to each side $y-1+1\geq1.5+1\longrightarrow$ add $y\geq2.5$ Check the endpoint. $2.5-1\overset?=1.5$ $1.5=1.5\checkmark$ Check the inequality. $3-1\overset?\geq1.5$ $2\geq1.5\checkmark$ Since 2.5 is included in the solution set, the endpoint of the graph will be a solid circle.
