**Steve**, Monday, August 13, 2012 at 3:21pmThe slope of the line segment joining (3,7) and (9,1) is -6/6 = -1.

Any point equidistant from those two points will lie on the perpendicular bisector of that line segment.

So, we want the line with slope=1, through (6,4), the midpoint of the segment.

y-4 = 1(x-6)

Now, we plug in (2,k) to get

k-4 = 2-6

k = 0
