Question
the end points of a line segment are A (-7, -1) and B (5,5)
determine the equation of right bisector of AB
show that the origin 0,0 lies on the right bisector of AB
determine the equation of right bisector of AB
show that the origin 0,0 lies on the right bisector of AB
Answers
Reiny
slope of AB = 6/12 = 1/2
slope of right bisector = -2
midpoint of AB = (-1,2)
equation of right-bisector
y-2 = -2(x+1)
y-2 = -2x - 2
y - 2x
it is obvious that (0,0) satisfies this equation, thus (0,0) lies on this line
