I'll write out what I need help with.
The endpoints of a line segment are A(-7,-1) and B(5,5).
a) Determine the equation of the right bisector of AB.
I have AB's midpoint as (-1,2), AB's slope as 1/2, and the slope of the right bisector as -2.
Therefore the equation of the right bisector of AB is y=-2x
I'm not sure if that's correct. Could someone look it over and see if I made any mistakes?
I also need help with two more questions;
b) Show that the origin, (0,0), lies on the right bisector of AB.
c) Determine the equation of the circle passing through AB.
I have no idea how to answer these questions. Can someone help me with them?
