[movement]make Line moving with Point

[Acpear]

落霞与孤鹜齐飞，垂线与白点共动……

The white point is an active point moving along on the Inverse proportion function: 1/x, what I want to solve is making the vertical yellow line moving together with the dot. The following picture displayed my code. How to add some codes to achieve my purpose?Thanks!
白点在反比例函数上运动，我想让黄线也伴随其运动，下面是代码，我应该添加什么代码来达到目的？谢谢！：）

Please paste the code instead of the screenshot.

And please avoid using Chinese here.

f1 = self.get_graph(x1, color=YELLOW, x_min=0.25, x_max=5)
f1name = MathTex("y=\frac{1}{x}").shift(self.coords_to_point(3, 3))
dot1 = Dot(point=self.coords_to_point(0.25, 4))
line1 = self.get_vertical_line_to_graph(0.25, f1, Line)
self.play(Create(f1), FadeInFrom(f1name, DOWN))
self.play(FadeInFromLarge(dot1)), self.play(FocusOn(self.coords_to_point(0.25, 4)))
self.play(Create(line1))
self.play(MoveAlongPath(dot1, f1), run_time=3, rate_functions=linear)

Requirements read, Okay~

Maybe line1.add_updater(lambda m: m.become(self.get_vertical_line_to_graph(dot1.get_x(), f1, Line))).
But I noticed that you are using the community version, so you'd better ask the question in their discord channel or open an issue in ManimCommunity/manim instead of here.

Thanks for your enthusiastic help! I get it!
