This is exactly the interesting part of this problem!
Can you prove what seems evident: that those three points must be collinear?

Doom Scrolling: Why Does Scrolling End in Doom? Scrolling is playing the lottery or the slot machines paid with by your time. With each pass down you expect something better and better. Except you get more and more disappointed. That "it" moment never arrives. The jackpot never occurs. The first scroll you find something nice. But then you want more and more. You keep expecting to find something better and better. *Scroll-down*---nothing! Scroll-down again. Nothing! You try to stop but you can't. Your dopamine receptors have become exhausted and you just gave yourself depression (doom) and ADHD.
