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 = [
`(1)/(2)` (x₁ + x₂ ) ,
`(1)/(2)` (y₁ + y₂ ) ]

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

midpoint = [
`(1)/(2)` ( - 1 - 7 ) ,
`(1)/(2)` (2 - 4 )] = (- 4, - 1 )
