Question

3.Find the midpoint of : 
(0,4)(3,13) 
(0.7)(2,-1) 
(10,5)(22,18)

Answer 1

  

Midpoint of two points = [ (x ₁ + x ₂) / 2, (y ₁ + y ₂) / 2 ].

• ( x ₁ , y ₁ ) = (0, 4) and ( x ₂ , y ₂ ) = (3, 13)

              Mid point = [ ( 0 + 3) / 2, (4 + 13) / 2 ]

                             = [ 3/2, 17/2 ].

• ( x ₁ , y ₁ ) = (0, 7) and ( x ₂ , y ₂ ) = (2, - 1)

              Mid point = [ ( 0 + 2) / 2, (7 - 1) / 2 ]

                            = [ 2/2, 6/2 ]

                            = [ 1, 3 ].

• ( x ₁ , y ₁ ) = (10, 5) and ( x ₂ , y ₂ ) = (22, 18)

             Mid point = [ ( 10 + 22) / 2, (5 + 18) / 2 ]

                            = [ 32/2, 23/2 ]

                            = [ 16, 23/2 ].
