It’s convention, I think. If I remember correctly, you always put y on the left, because you can also write equations as functions of a variable, x, with the symbology f(x) = mx + b. That way you can integrate and derive the function easily, since m and b are constants, and all your x variables are on one side.
If I were to encounter x = my + b, the first thing I would do, just by nature at this point, would be to convert it to y = (x - b) / m.
It’s been a while since I took math, and I was never the best, so others should feel free to correct me.

The path of a bullet is parabolic. You ain't hitting shit with that math, yo.

At that range, using a linear estimation is fine I assure you

Both linear linear and parabolic descriptions of a bullet trajectory are approximations of a drag curve, that can be obtained only numerically.

On short distance you do

That's just what they want you to think

Define x motherfucker

Serious question: is x = my + b also a slope intercept? Why is it only calculated via the y axis?

....... I may have 3am brain, but the intercept is y=b....
Slope intercept formula???
That's a formula for a line, y intercept is x=0...

Ok, but what's the quadratic formula?

Or you can take it's derivative at that point
