Hello, I can't understand 2 questions from my math homework can you please explain how I am supposed to do that? 1. Find the equations of the medians of the triangle with vertex coordinates at J(2,-2) K(4,-1) and L(-2,-5). 2. Find the equation of the perpendicular bisector of a chord of a circle, given that the end points of the chord are C(-2,0) and D(4,-4). Thanks a lot!
