Methods of solving LPP: a graphical method

You have the following linear programming problem:

$$Maximize \ z = 5x + 3y$$

Subject to the following constraints:

$$3x + y \le 6 \\ x + 0.6y \le 2.4 \\ x + 1.5y \le 5.625 \\ x, y \ge 0$$The constraints are shown in the graph below:

Find the corner point(s) that maximize the objective function
