Erect Two Points Line 纵向双点线
Two Points Line 双点线
points-line meshing 点线啮合
points-line meshing gear 点线啮合齿轮
Line End Points 直线的端点

Line From Points 点生成线体
The line cuts the circle at two points.
那条线与圆相交于两点。
The line is made up of the succession of plotted points.
这条线是由连续的标绘点组成的。
So, OK, it's pretty good because we have two points in that line.
这非常好,因为我们有了直线上的两个点。
What Gauss did was said, let's fit a line through the point-- the scatter of points--and that's called the regression line.
高斯说,做这样的一条直线,切合所有散点,这就是回归直线
He chose the line so that--this is Gauss-- he chose the line to minimize the sum of squared distances of the points from the lines.
高斯选的这条线,所有点距离这条直线的平方和,是所有直线中最小的
That's a choice, and that choice turns out to be very interesting and really important, because if you connect these two points together, you get a straight line that has to intercept the x-axis at some point.
在这一选择下,我们会发现一件非常有趣,而且极其重要的事,当你把这两点用直线连接起来,你会发现这条直线,将与x轴在某点相交。
