do you know that there is no mathematical formula for lines?

Did you know you are talking nonsense?
y=mx+c

[aetzbar (OP)]

The formula you describe describes the position of points in the plane.
Can you view a formula that describes a line?

The formula you describe describes the position of points in the plane.
Can you view a formula that describes a line?

Not that it's important to the OP;
What's the difference?

If pi was incorrect, engineers who develop jet engines for example, would have discovered it decades ago with catastrophic engine failures.

The idea of pi changes, has no effect on technology practice.
The effect is on the mathematicians' perception of reality.
They determined and even proved a wrong idea, which they teach for hundreds of years.
Mathematicians delayed the development of geometry.
This geometry produces a new fixed number (1.007) that will also appear in the physical field

That's plainly nonsense.
Why do you keep saying it?
