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.

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