How to align groups of vertices along the same axis with a hard reference to the coordinate grid?

Question

Blender

What is the correct way to align multiple vertices rigidly on the same axis? I ask because blender, when choosing from 3 points when inserting an exact number in Transform -> Medium -> Y, somehow strangely assigns this value. Maybe instead of 75 put 73, another point, 74, and the third 74.5. Where is it disabled/enabled?

I'll answer my own question. You need to select the settings Pivot Point (Pivot point) - Active Element. Then you can align using S - Y/X/Z - 0 on the active point.
We don’t really need other settings, because. they align relative to some point while maintaining the deformation of the object.
