Question

On a number line suppose point E has a coordinate of 3,EG=6,and Ex=12.is point G the midpoint of EX?what are possible coordinates for G and X?

Answer 1

G is not necessarily the midpoint of EX, G could be at -3 or +9 and X could be at -9 or +15. If G and X are on the same side of E, then G is at the midpoint of EX, if they are on opposite sides, G is not the midpoint of EX.
