On a number line, point A has coordinate 5, and point D is on the line such that AD = 8. What are two possible coordinates of point D?

Answer 1

D could be to the right of A, then D = 13
D could be to the left of A, then D = -3

Answer 2

if on a number line the points are coordinates -2 and 5, then they are 7 units apart

Answer 3

If the midpoint of a segment is (8, 14) and one endpoint is (-9, -1), what are the coordinates of the other endpoint?

(25, 29)

(29, 25)

(-29, -25)

(-25, -29)
