Question

What is the midpoint of the line segment graphed below?
(-1,2)
(9,5)

Answer 1

(4, 2.5 )

Explanation:

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

(
`(x_(1)+x_(2) )/(2)`,
`(y_(1)+y_(2) )/(2)` )

Here (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (9, 5) , then

midpoint = (
`(-1+9)/(2)`,
`(2+5)/(2)` ) = (
`(8)/(2)`,
`(7)/(2)` ) = (4, 3.5 )

Answer 2

1,3
