Question

Find the midpoint of the segment with the following endpoints.
(9,9) and (1,-1)

Answer 1

(5, 4)

Explanation:

`\boxed{midpoint = ( (x1 + x2)/(2) , (y1 + y2)/(2)) }`

(X₁, Y₁) is the coordinates of the 1st point and (X₂, Y₂) is the coordinates of the 2nd point.

Using the formula above,

`midpoint \: of \: segment \\ = ( (9 + 1)/(2) , (9 - 1)/(2) ) \\ = ( (10)/(2) , (8)/(2) ) \\ = (5,4)`
