$b\gt-4$
$-\frac{3}{2}b\lt6\longrightarrow$ multiply both sides by $-\frac{2}{3}$; reverse the inequality sign $-\frac{3}{2}b\times(-\frac{2}{3})\gt6\times(-\frac{2}{3})\longrightarrow$ multiply $b\gt -4$ Check the inequality. $-\frac{3}{2}(0)\overset?\lt6$ $0\lt6\checkmark$ Since -4 is not included in the solution, the endpoint of the graph is an open circle.
