7 A curve has equation
$$y = \frac { 3 x - 1 } { x + 2 }$$
- Write down the equations of the two asymptotes to the curve.
- Sketch the curve, indicating the coordinates of the points where the curve intersects the coordinate axes.
- Hence, or otherwise, solve the inequality
$$0 < \frac { 3 x - 1 } { x + 2 } < 3$$
