It would be the vertical distance between that point and the line.

这将是该点和线之间的垂直距离。

And what that is, is you take each of these data points' vertical distance to the line.

这就是，你把每个数据点的垂直距离带到线。

So for each of these points, the error between it and the line is the vertical distance.

所以对于这些点中的每一个，它与直线之间的误差就是垂直距离。

Divide that by the vertical distance from where the ladder hits the wall to our axis of rotation, and we get 36.8 Newtons: the force from the wall on the ladder.

将其除以从梯子撞击墙壁的位置到我们的旋转轴的垂直距离，我们得到 36. 8 牛顿：梯子上的墙壁的力。
