Question

What methods could you use to calculate the x-coordinate of the midpoint of a horizontal segment with the endpoints of (-20, 0) and (20, 0)?

A. divide 2 by 20
B. take the average of the endpoints
C. divide 0 by 20
D. calculate the average of the x-coordinates
E. divide 20 by 2

Answer 1

D and E I think.....

Answer 2

option B and D

Explanation:

we need to calculate the x-coordinate of the midpoint of horizontal line segment

To find midpoint of x coordinate , add the x coordinate of the given points and divide by 2

(-20, 0) and (20, 0)

The x coordinates of end points are -20 and 20

`(-20+20)/(2) =0`

HEre we divide 0 by 2 not 0 by 20

WE take the average of the endpoints

or calculate the average of the x coordinates
