Question

What is the y-intercept of the line that is the perpendicular bisector of the segment joining (-3,-4) and (5,10)? express you answer as a mixed number?

Answer 1

My geometry program shows the equation of the bisector to be
.. 4x +7y = 25
When x = 0, the y-value is 25/7 = 3 4/7

The y-intercept is 3 4/7.
