The perpendicular bisector of the line segment \overline{ab} is the line that passes through the midpoint of $\overline{ab}$ and is perpendicular to \overline{ab}. find the equation of the perpendicular bisector of the line segment joining the points (1,2) and (7,4). enter your answer in the form "y = mx + b."

Hmmm so hmmm we know AB has the points A(1,2) and B(7,4).

alrite... so the bisector passes through its midpoint... what's the midpoint of AB anyway?



so it goes through 4,3, is a segment perpendicular bisector, that means the slope of it will be the negative reciprocal slope of AB, hmmmmm what's the slope of AB anyway?



alrite.... so what is the negative reciprocal of that anway?



ahha, so, we're really looking for the equation of a line that has a slope of -3, and runs through 4,3 then,

No i refuse to tell you the answer but the estimate is 10
