slope = .010414546538
intercept = 1525424.85897

The slope needs to relate to a clockwise direction from 0 - 360 degrees.

I'm using the standard analytic geometry slope/intercept form y = mx + b, where m is the slope and b is the intercept: https://www.chilimath.com/lessons/interm...cept-form/

This is also what the LR function uses.

It shouldn't be too hard to convert to what you need.
