The graph shows the system of equations:

1. $y = \frac{2}{3}x + 4$ (blue line)
2. $y = -x - 1$ (red line)

The intersection of these lines represents the solution to the system. The lines intersect at the point $(3, 1)$, which is the solution to the system of equations.

So, the solution is: $x = 3, \quad y = 1$
