Question

What happens if two straight lines intersect at the origin?

Such as the equations y=2400x and y=60x

Answer 1

The lines make some angles at the origin where they meet. Here we see the tangent of the first is 2400 (almost vertical) and the tangent of the other is `60`, also nearly vertical, so the tangent of the small angle between them will be

`(2400 - 60)/(1+2400(60)) = 180/11077`

corresponding to a teeny angle of around `0.9^circ.`

Oops, that's trig, not algebra
