Indicate the equation of the line that is the perpendicular bisector of the segment with endpoints (4, 1) and (2, 5).

midpoint is ( (4+2)/2 , (15)/2 ) = (3,2)
slope for given points line = (1+5)/(42) = 3
so slope of perpendicular is 1/3
so y = (1/3)x + b
sub in (3,2)
2 = (1/3)(3) + b
b = 1
equation : y = (1/3)x 1
