You can tell by looking at the position graph (which shows an almost straight line) as well as the velocity graph where the slope clearly changes.

只要看看那条接近直线的时间-纵坐标图像和斜率明显变化的速度-时间图像，你就可以明白了。

Regression software programs graph the sample points and give the (cost-function) formula of the straight line that best fits the points.

回归软件程序将样本点用图表示，并且给出最拟合样本点的直线的价值函数公式。

This paper presents an algorithm for solving a complete monotonic chain set in the planar straight line graph g.

本文提出求平面直线图完全单调链集的一种算法。

So here we have energy increasing on the y-axis, and you see this straight line at the bottom here is lower down on the graph, and that's the energy of a bound electron, so that's going to be a low stable energy.

这里我们看到能量沿着y轴增加，而且在这张图片上,这条直线在底部是降低的，那是一个束缚电子的能量，所以那是一个低稳态能量。
