Question

find the co-ordinates of P on the line joining the points A(6,-3),B(-8,-7) such that AP / PB = 1

Answer 1

Let A(6,-3) and B(-8,-7) and let P(x,y) divide AB
such that AP = PB

coordinates of p =  ([x₁+x₂]/2) , ([y₁+y₂]/2)

                   (x,y) =  ([6-8]/2 , [-3-7]/2)

                           =  (-1 , -5)

thus coordinates of P = (-1 , -5)
