$-6$
The product of two numbers with opposite signs is negative while the product of two numbers with the same sign is positive. Hence, the given expression, $-\dfrac{8}{3}\cdot\dfrac{9}{4}$, simplifies to \begin{array}{l}\require{cancel} -\dfrac{72}{12} \\\\= -\dfrac{\cancel{12}\cdot6}{\cancel{12}} \\\\= -6 .\end{array}
