Identify the equation in point-slope form for the perpendicular bisector of the segment with endpoints b(−1,1) and c(−5,−7). !

Equation in point-slope form=  

Step-by-step explanation:

The given end points are B(−1,1) and C(−5,−7)

Mid point M of BC= ,

Mid point M of BC = -3 , -3

Slope of BC =   = 2

Slope of bisector= m=

Equation of perpendicular bisector :

                                                           ⇒  

                                                          ⇒   2(y+3)= -(x+3)

                                                          ⇒  

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

answer: it's d
