    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)


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

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

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

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

    So [tex] y - 1 = -\frac{1}{2}( x-14) [/tex]
