#### Answer

y≥2.5

#### Work Step by Step

Find the solution by isolating the variable, y, on one side of the inequality.
y−1≥1.5⟶ add 1 to each side
y−1+1≥1.5+1⟶ add
y≥2.5
Check the endpoint.
2.5−1=?1.5
1.5=1.5✓
Check the inequality.
3−1≥?1.5
2≥1.5✓
Since 2.5 is included in the solution set, the endpoint of the graph will be a solid circle.
