Question

write an equation in point slope form for the perpendicular bisector of the segment with endpoints M(-1,-3)and N (7,1)

Answer 1

slope of segment here = 4/8 = 1/2

slope of perp needs to equal -2
.....................................................

midpoint of segment = (3,-1) so include that as a point:

y = -2(x-3)+1

y = -2x + 7 maybe?

Answer 2

point slope form...ok

(y--1) = -2(x-3)

Answer 3

so my slope int form was off by 2 :)

Answer 4

thanks so much! =)
