Triangle Problem: Calculate Perpendicular Bisector

[mr.mair]

assignment question URGENT!

I having trouble and its urgent some one help
Triangle wit the vertices A(6,-15)B(22,17)and C(24,11)

-midpoint of side A = (14,1)

Question

1.Calculate the equation of the line that is perpindicular bisector of the side triangle.

 

[courtrigrad]

Use the fact that m_{2} = -\frac{1}{m_{1}} for a perpendicular line.

i Still do not get it

 

[mr.mair]

but how do i figure out the equation of the line

The slope of AB is 2. So the slope of the perpendicular bisector is -\frac{1}{2}.

So use the equation y-y_{1} = m(x-x_{1}).

So y - 1 = -\frac{1}{2}( x-14)
