Question

If the endpoints AB of have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of ? AB

Answer 1

Answer and Step-by-step explanation:

Answer 2

(4,3)

Explanation:

The coordinate of midpoint of two end points (x1,y1) and (x2, y2) is given by

`( (x1 + x2)/(2) \: \: \: \: \: (y1 + y2)/(2) )`

Here, x1=9 y1=8

x2=-1 and y2=-2

So the midpoint of AB is

`( (9 + ( - 1))/(2) \: \: (8 + ( - 2))/(2) \: )`

`((9 - 1)/(2) \: \: (8 - 2)/(2) \: \: ) \\ ( (8)/(2) \: \: (6)/(2) \: )`

(4,3)
