Mr. Brown was going away for a week. Before he left, he said to his son, "if anyone asks for me, you can tell him that your father has been out for doing something, and will be back in a week, then be sure to ask him to sit down for a cup of tea."
    "OK, Dad," said his son. But he was afraid his son couldn't remember this, he wrote these words down on a piece of paper and gave it to him. His son put it into his small pocket, took it out and looked at it every now and then.
    Four days passed, but no one came to see his father. The boy thought that there was no man to come and that the piece of paper was of no more use for him, so he burnt it that evening.
    The next afternoon, someone knocked at the door. The boy opened it. A man was standing at the door and said, "Where is your father?" The boy put his hand into his pocket at once and looked for the piece of paper. He could not find it. He suddenly remembered he had burnt it, so he shouted, "No more."
    The man was very surprised. He asked, "No more? I met your father last week. When did it happen?" "Burnt yesterday evening."

在平面直角坐标系xoy中，以O为极点，x轴的正半轴为极轴的极坐标系中，直线l的极坐标方程为θ=$\frac{\mathrm{\pi }}{4}$，曲线C的参数方程为$\left\{\begin{array}{c}x=\sqrt{2}\cos \theta \\ y=\sin \theta \end{array}\right.$．

（1）写出直线l与曲线C的直角坐标方程；

（2）过点M平行于直线l₁的直线与曲线C交于A、B两点，若|MA|•|MB|=$\frac{8}{3}$，求点M轨迹的直角坐标方程．
