Answer:
The possible coordinates of the midpoint are 3 and -3
Step-by-step explanation:
The given information are;
The coordinate of the point A on a (horizontal) number line = 0
The length of AR =
The coordinate of the midpoint of AR are given as follows;
Coordinate of the midpoint = Coordinate of A ± (Length of AR)/2 which gives;
The possible coordinates of the midpoint as 0 + 6/2 = 3 or 0 - 6/2 = -3
The possible coordinates of the midpoint are 3 and -3
