So I'm looking at all points to satisfy 2 X minus Y equal 0. And I'm often... it's often good to start with which point on the horizontal line, on this horizontal line Y is 0.
找寻所有的点满足2X-Y=0.最好从横坐标上的点为起始,横坐标也就是Y=0。
Since horizontal menus are simply lists in a horizontal line, let's start the process with a list.
因为横向菜单只列在一个横向的一行,让我们从一个列表开始这个过程。
So the pink line is going to move towards the vertical, and the blue line is going to move towards the horizontal, and notice that the amount of effort that we generate, goes down dramatically, goes down in this direction.
粉色的线最后会趋向垂直,蓝色的线最后会趋向水平,请大家注意下我们付出的努力,会朝这个方向大幅减少
