7-114.
Let
Find the distance from
to . Make a sketch of the points and use the Pythagorean Theorem to find the distance between the points.
Write the equation of the perpendicular bisector for
in point-slope form. You need a point (midpoint) and the slope of the perpendicular line so that you can use the point-slope form of a line.
Find the midpoint by:
Perpendicular slope would be negative the reciprocal of the slope between
and .
