Question

Find the coordinates of the midpoint M
(-3, 2) and K(9, 2)

Answer 1

(3,2)

Explanation:

since -3 + 9 =6

6 ÷ 2 =3

2 + 2 = 4

4 ÷ 2 = 2

therefore (3,2)

Answer 2

M = (3, 2 )

Explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint (M) is

M = (
`(x_(1)+x_(2) )/(2)` ,
`(y_(1)+y_(2) )/(2)` ) ← midpoint formula

let (x₁, y₁ ) = (- 3, 2 ) and (x₂, y₂ ) = (9, 2 ) , then

M = (
`(-3+9)/(2)` ,
`(2+2)/(2)` ) = (
`(6)/(2)` ,
`(4)/(2)` ) = (3, 2 )
