Question

find the coordinates of the midpoint of (-1,2 ) and (-7-4)

Answer 1

( - 4, - 1 )

given 2 points ( x₁ , y₁ ) and ( x₂ , y₂ )

the coordinates of the midpoint are

midpoint = [ $\frac{1}{2}$ (x₁ + x₂ ) , $\frac{1}{2}$ (y₁ + y₂ ) ]

here (x₁ , y₁ ) = ( - 1 , 2 ) and (x₂ , y₂ ) = ( - 7, - 4 )

midpoint = [ $\frac{1}{2}$ ( - 1 - 7 ) , $\frac{1}{2}$ (2 - 4 )] = (- 4, - 1 )
