Asked by Jamie
The "perpendicular bisector" of the line segment $\overline{AB}$ is the line that passes through the midpoint of $\overline{AB}$ and is perpendicular to $\overline{AB}$.
The equation of the perpendicular bisector of the line segment joining the points (1,2) and (-5,12) is y = mx + b. Find m+b.

find the slope and midpoint of the segment
the bisector passes through the midpoint
the slope of the bisector (perpendicular) is the negative reciprocal of the slope of the segment
the bisector passes through the midpoint
the slope of the bisector (perpendicular) is the negative reciprocal of the slope of the segment

Also how do you find slope?

When it has the latex do you mean the line is over the AB?

Yes, I do.

Slope= y2-y1/x2-x1
