$-4\frac{13}{16}$

When $x=\frac{3}{4}$ and $y=-\frac{4}{7}$, $=\frac{2+x}{y}$ $=(2+x)\div(y)$ $=(2+\frac{3}{4})\div(-\frac{4}{7})$ $=(\frac{8}{4}+\frac{3}{4})\div(-\frac{4}{7})$ $=(\frac{11}{4})\div(-\frac{4}{7})$ $=-(\frac{11}{4}\div\frac{4}{7})$ $=-(\frac{11}{4}\times\frac{7}{4})$ $=-\frac{77}{16}$ $=-4\frac{13}{16}$
