Midpoint of (3,1) & (5,3)

Question

the lines are T & U  i dont kno the midpoint formula

Answer 1

midpoint formula:     ( x₁ + x₂)/2 = x_mid     (y₁+ y₂)/2 = y_mid

 

point 1:  (3,1)

 

point 2: (5,3)

 

so,     (3 + 5)/2 = 8/2 = 4 = x_mid

 

         (1 + 3)/2 = 4/2 = 2 = y_mid

 

therefore,   (x_mid, y_mid) = (4,2)
