I took a break, had a cookie, punched a wall, came back, realized the 0's they were using were the coordinates of the origin to prove that it was on the line.
Alright so I've been trying to wrap my head around this for a bit now, got through most of it, but there's this one part that's just not clicking.
The question is for me to "Show that the origin, (0, 0), lies on the right bisector of AB."
The following is a copy/paste of the question I'm working on, my particular question starts at "c" which is about half way down, it also shows me the solution, but what I don't understand is the explanation of the solution, or what it's doing to prove that the origin lies on the right bisector of AB.
If you could explain it to me in in the simplest way possible as to how they're using the equation of the bisector to show this, it would be much appreciated.
