On a number line, suppose the coordinate of A is 0, and AR = 6. What are the possible coordinates of the midpoint of AR? The possible coordinates for midpoints of the segment are
?

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
